=Changelog between 1.0.28 and 1.0.29 releases=
==alsa-python==
===Core===
: - Release v1.0.29
:
: - setup.py: indent changes
:
===pyalsa.alsaseq module===
: - alsaseq: fix memory leaks
:
: Fix a bunch of dangling reference issues. Also switch to Py_BuildValue
: where appropriate, since that makes it easier to build complex
: dictionary/tuple structures without leaking integer/string references.
:
: - alsaseq: remove dead code in Sequencer_set_clientname()

=Detailed changelog between 1.0.28 and 1.0.29 releases=
=Changelog between 1.0.28 and 1.0.29 releases=
==alsa-lib==
===Core===
: - Release v1.0.29
:
: - conf/ucm: GoogleNyan: Add configuration
:
: Taken from the ChromeOS sources, this configuration should apply to all
: Nyan boards from Google, so far HP Chromebook 14 (nyan-blaze) and Acer
: Chromebook 13 (nyan-big).
:
: - conf/ucm: PAZ00: add Toshiba AC100/Dynabook AZ new config
:
: Recent mainline kernels threat Toshiba AC100 audio hardware as hw:PAZ00
: vs old hw:tegraalc5632.
:
: This patch adds config files for new hw name and include them to
: makefiles.
:
===Control API===
: - control: complement comment for subscribe API
:
: When minus value is given as a parameter, the API returns whether
: the caller has already subscribed or not.
:
: This commit adds a comment about this so as better documentation.
:
: - Remove unused hostname resolution in shm plugins and aserver
:
: PCM and control shm plugins and aserver have some codes to resolve the
: host address and check whether it's a local host although the given
: address is never used. In addition, the code contains gethostbyname()
: that is known to be obsoleted. So, let's get rid of all these unused
: codes.
:
: The host configuration item is still accepted (but just ignored) for
: keeping the compatibility.
:
: - control: enable octal and hexadecimal parse
:
: Use zero-base for strtol(), so get_integer() and get_integer64()
: can parse decimal, octal and hexadecimal data from input string.
:
: - control: return negative value in case of error
:
===HWDEP API===
: - hwdep: add OXFW driver support
:
: Linux 3.19 newly support this driver. By hardware dependent interface,
: userspace applications can get hardware information, lock/unlock kernel
: streaming and receive lock status event.
:
: - hwdep: add missing declaration for snd_hwdep_poll_descriptors_count()
:
: The alsa-lib has 'snd_hwdep_poll_descriptors_count()' but hwdep.h has no
: declaration for the function. No applications can call the function just
: by including the header.
:
: This commit adds a line to the file for this function.
:
: - Sync enum snd_hwdep_iface_t with include/asound/asound.h
:
: Some members in this enumerated type has not updated for 9 years, although
: kernel-drivers added them during this period. This commit adds them following
: to a commit 87df9f3 'sync include/asound/asound.h with 3.17-rc1 kernel'.
:
===Mixer API===
: - mixer: Fix unused parameter warnings
:
: mixer_simple.h:35:64: warning: unused parameter 'mixer' [-Wunused-parameter]
: static inline int snd_mixer_simple_basic_register(snd_mixer_t *mixer,
: ^
: mixer_simple.h:36:40: warning: unused parameter 'options' [-Wunused-parameter]
: struct snd_mixer_selem_regopt *options,
: ^
: mixer_simple.h:37:29: warning: unused parameter 'classp' [-Wunused-parameter]
: snd_mixer_class_t **classp)
: ^
:
: - mixer: Fix inclusion of config.h
:
: config.h wasn't read or read too late in some files in src/mixer.
:
: - mixer: Fix missing hctl handle free in snd_mixer_attach_hctl()
:
: Yet another missing piece.
:
: Also, update the function document to warn about the behavior at
: error.
:
: - simple_abst: null check for lib
:
: - mixer: fixed double free
:
===PCM API===
: - Remove unused hostname resolution in shm plugins and aserver
:
: PCM and control shm plugins and aserver have some codes to resolve the
: host address and check whether it's a local host although the given
: address is never used. In addition, the code contains gethostbyname()
: that is known to be obsoleted. So, let's get rid of all these unused
: codes.
:
: The host configuration item is still accepted (but just ignored) for
: keeping the compatibility.
:
: - pcm: fix buffer overflow in snd_pcm_chmap_print()
:
: The size argument is wrong for one of the snprintf() calls in
: snd_pcm_chmap_print(), allowing an overflow to happen (the user-provided
: buffer may be written data up to 2x its actual size).
:
: Seen in an user report here: http://trac.kodi.tv/ticket/15641
:
: - pcm: Fix assorted tstamp_type bugs/omissions.
:
: Just a couple of quick fixes related to tstamp_type.
:
: - snd_pcm_sw_params(): copy tstamp_type field
: - snd_pcm_tstamp_type_name(): fix argument type
: - snd_pcm_dump_sw_setup(): fix dumping of tstamp_type field
:
: - pcm: Fix DSD sample format endianess and add big-endian format
:
: This patch adds big-endian DSD sample format and fixes return value of DSD
: formats for snd_pcm_format_little_endian().
:
: - pcm: dmix: Don't ignore SND_TIMER_EVENT_MSTOP
:
: When a slave PCM gets an error like XRUN, it stops and notifies with
: SND_TIMER_EVENT_MSTOP event. But the current code filters out this
: type and eventually hang due to the empty timer queue. The fix is to
: just add this event type to the filter bit mask.
:
: - pcm: return negative value in case of error
:
: - pcm_hooks: null check for h
:
: - pcm_share: fixing missing mutex unlock
:
: - pcm_file: fixed missing free
:
: - pcm, rate: hw_avail must not be negative before starting the stream
:
: If it is, then it means most likely the driver problem, so we should
: return error immediately instead.
:
: - pcm route: Fix the bad condition (always false)
: - Revert "pcm: rewindable, forwardable: don't return stale data"
:
: This reverts commit 6db0fe495ef1db1fd8f0ed791996f834665a926b.
: - pcm, file: don't recurse in the rewindable and forwardable callbacks
:
: - pcm: rewindable, forwardable: don't return stale data
:
: The current behavior of snd_pcm_rewindable and snd_pcm_forwardable means
: that the returned value is only accurate to one period. Or maybe even
: meaningless if period interrupts are off. Fetch the up-to-date position
: of the hardware pointer, as that's what is wanted by callers.
:
: - dsnoop: rewindable and forwardable logic was swapped
:
: - rate: handle negative values from snd_pcm_mmap_playback_hw_avail
:
: Such negative returns are possible during an underrun if xrun detection
: is disabled.
:
: So, don't store the result in an unsigned variable (where it will
: overflow), and postpone the trigger in such case, too.
:
: - pcm, null: use the snd_pcm_mmap_avail function
:
: instead of the open-coded equivalent
:
: - pcm, rate: use the snd_pcm_mmap_hw_avail function
:
: instead of the open-coded equivalent
:
: - pcm: handle negative values from snd_pcm_mmap_hw_avail
:
: Such negative values can happen when an underrun happens and xrun
: detection is disabled. Another situation is if the device updated the
: pointer before alsa-lib has a chance to detect the xrun.
:
: The problem is that these negative values could propagate to the
: snd_pcm_rewindable return value, where it is specified that negative
: returns must be interpreted as error codes and not as negative amount of
: samples.
:
: - pcm: express the rewind size limitation logic better
:
: There are a few places where the argument of the .rewind or .forward
: callback is checked against the same value as returned by .rewindable or
: .forwardable. Express this "don't rewind more than rewindable" logic
: explicitly, so that the future fixes to the rewindable size can go to
: one function instead of two.
:
: While at it, take advantage of the fact that snd_pcm_mmap_avail() cannot
: return negative values (except due to integer overflow, which is AFAICS
: impossible given the current boundary choice).
:
: - dmix: actually rewind when running or being drained
:
: - pcm: add new 32-bit DSD sample format
:
: Add the new DSD_U32_LE sample format to alsa-lib.
:
: NB include/pcm.h and include/sound/asound.h are updated so a new sync with the
: kernel headers is not needed
:
: - pcm: fix return value of snd_pcm_share_slave_avail
:
: The return value was wrong for playback if slave->hw_ptr was near the
: boundary and *pcm->appl.ptr was near zero. The wrong result was greater
: than the boundary.
:
: - pcm: fix snd_pcm_mmap_hw_avail() near the boundary
:
: This function returned incorrect results when hw.ptr was near the
: boundary and hw.appl_ptr was near zero. Here "incorrect" means "greater
: than the boundary".
:
: The result was incorrect, because it was used as a return value of
: various *_rewindable() functions and also as the delay for ioplug.
:
: - pcm: 2nd round of pcm_misc DSD fixes
:
: Functions 'snd_pcm_format_silence_64' and 'snd_pcm_format_size' also need to be
: able to handle the DSD smaple format.
:
: Changes from v1:
: - Correct silence pattern for DSD
:
: - pcm: Add missing signed and endianess definitions for DSD formats
:
: - pcm: Fix DSD formats userland usability
:
: Support for DSD sample formats has been added a while ago. This patch makes
: those sample formats beter usable from userland (e.g. aplay).
:
: [These implementation details have been forgotten in the previous DSD
: support patch -- tiwai]
:
: - pcm: pcm_local.h: include <time.h> to enable CLOCK_MONOTONIC
:
: CLOCK_MONITONIC is defined in <bits/time.h>, add <time.h> before
: <sys/time.h>.
:
: - pcm: Drop snd_pcm_linear_{get|put}32_index()
:
: These are identical with snd_pcm_linear_{get|put}_index().
:
: - pcm: route: Use get32 for multi-source route calculation
:
: The PCM route plugin can assign the destination value from average of
: multiple sources with attenuation. This requires the read of each
: channel value, sums and writes the resultant value in the requested
: format.
:
: Currently, get_labels is used for reading source values while
: put32_labels is used for writing the dest value. This is, however,
: a buggy implementation; get_labels gives the value as is only with
: endianness and signedness conversions, but put32_labels assumes that
: the value is normalized to 32bit int and it shifts down to the dest
: format. In addition, the current code lacks get_labels entries for
: the 24bit formats, as Shengjiu Wang spotted out.
:
: For fixing these bugs, this patch replaces the read with
: get32_labels and use always 64bit int for sum. This simplifies the
: code a lot and drops many lines.
:
: - pcm: Fill sw_params proto field
:
: Fill the new proto field introduced to sw_params with the current PCM
: protocol version. This makes tstamp_type evaluated properly in the
: kernel.
:
: - pcm: route: Use get/put labels for all 3 byte formats
:
: So far, use_getput flag is set only when the src or dest format is
: 24bit physical width. But, also 18 and 20 bit physical width formats
: should set the flag, too. This patch makes the check broader to cover
: all 3 bytes formats.
:
: - pcm: Implement timestamp type handling in all plugins
:
: Now all PCM plugins do support the proper timestamp type or pass it
: over slaves. The internal monotonic flag is dropped and replaced with
: tstamp_type in all places.
:
: - pcm: Implement timestamp type setup in hw plugin
:
: This patch implements the support for sw_params timestamp type in PCM
: hw layer. As gettimestamp() is still unchanged, the resultant
: timstamps may be still with CLOCK_MONOTONIC even if you pass monotonic
: raw type. More fixes will follow.
:
: - pcm: Add sw_params API functions to get/set timestamp type
:
: For obtaining / changing the timestamp type, add the corresponding
: sw_params accessor API functions together with the public definitions
: of timestamp types.
:
: This patch only adds the functions and defines but doesn't bring the
: functional changes yet.
:
: - pcm: rate: fix hw_ptr exceed the boundary
:
: For long time test case, the hw_ptr will exceed the boundary, then cause
: the avail size wrong.
:
===RawMidi API===
: - rawmidi: close handle h
:
===Use Case Manager API===
: - ucm: fix some variable constness issues
:
: I submitted earlier a patch that made the value parameter of
: snd_use_case_get() non-const, but as that changed the public API, the
: patch couldn't be accepted. This is the same patch, modifying the
: internal code so that there are fewer issues with constness, but the
: public API is left alone (a comment was added to the function
: documentation, though, so that hopefully nobody else will try to fix
: the same unfixable problem).
:
: - ucm: fix the logic of choosing the default cdev
:
: If the cdev has not been configured explicitly, use the PlaybackCTL
: or CaptureCTL value if one of them is set. If neither are set, or if
: both are set to different values, then there's no sensible default, so
: executing the sequence should fail. The previous code probably tried
: to implement this logic, but it was buggy.
:
: Also use more descriptive variable names than "cdev1" and "cdev2".
:
: - ucm: fix incorrect error code sign
:
: Reported-by: Takashi Iwai <tiwai@suse.de>
: - ucm: fix variable mixup
:
: I assume the intention was to use cdev1 for PlaybackCTL and cdev2 for
: CaptureCTL, but cdev1 was being used for both and cdev2 was not used
: for anything.
:
: - ucm: add binary configure file parse
:
: with cset command, UCM set kcontrol parameters directly:
: cset "name='<KCONTROL_NAME>' 1<,2,3,...>"
: This patch enables UCM to set kcontrol with parameters from
: configure file:
: cset-bin-file "name='<KCONTROL_NAME>' <path/to/file>"
: where "cset-bin-file" is a newly added keyword alongside of "cset",
: to indicate cset with binary data in file.
: The binary data in file is parameter for audio DSPs, and it's just
: passed by UCM/ALSA as raw data. The data type of parameter elements
: must be byte, and the count must matches driver definition.
:
: - ucm: Fix uninitialized err in snd_use_case_set()
:
: The compiler warns like:
: main.c:1664:9: warning: 'err' may be used uninitialized in this function [-Wmaybe-uninitialized]
:
: and actually there are slight code paths that slip.
: This patch adds the proper initializations to 0 to return the success
: code in these code paths.
:
: - ucm: Document PlaybackPCMIsDummy and CapturePCMIsDummy values
:
: At least PulseAudio needs special handling for dummy devices. To allow
: that to happen automatically, the UCM configuration should contain the
: information about which PCMs are dummy.
:
===/include/Makefile.am===
: - autotools: fix ucm partial build
:
: When --disable-ucm configure option is specified,
: don't install related include file.
:
===ALSA Server===
: - Remove unused hostname resolution in shm plugins and aserver
:
: PCM and control shm plugins and aserver have some codes to resolve the
: host address and check whether it's a local host although the given
: address is never used. In addition, the code contains gethostbyname()
: that is known to be obsoleted. So, let's get rid of all these unused
: codes.
:
: The host configuration item is still accepted (but just ignored) for
: keeping the compatibility.
:
===Configuration===
: - conf: add support for USB AudioSport Quattro (tm)
:
: This patch resulted from discussion with redlion_ on #alsa IRC channel
: on Freenode. 4-channel playback now works. 4-channel capture works too,
: but not simultaneously with playback (hardware limitation).
:
: Alsa-info before the fix:
: http://www.alsa-project.org/db/?f=a3673622074b88a1abf4ccc6e7f37d0b5b72f34a
:
: - conf/ucm: GoogleNyan: Add configuration
:
: Taken from the ChromeOS sources, this configuration should apply to all
: Nyan boards from Google, so far HP Chromebook 14 (nyan-blaze) and Acer
: Chromebook 13 (nyan-big).
:
: - USB-audio: Add five more cards to IEC958 blacklist
:
: These devices do not have any IEC958 outputs, so prevent them from
: being opened.
:
: - USB-Audio: Add Scarlett 2i4 USB to S/PDIF blacklist
:
: Like Scarlett 2i2, the 2i4 does not have any S/PDIF connections.
:
: - conf/ucm: PAZ00: add Toshiba AC100/Dynabook AZ new config
:
: Recent mainline kernels threat Toshiba AC100 audio hardware as hw:PAZ00
: vs old hw:tegraalc5632.
:
: This patch adds config files for new hw name and include them to
: makefiles.
:
: - conf: return negative value in case of error
:
: - USB-Audio: Add second S/PDIF device on Phiree U2
:
: Phiree U2 has an unusual configuration. It only has S/PDIF output, but
: there are still two devices presented:
: - device 0: PCM audio, subject to volume control
: - device 1: non-PCM data (passthrough), not subject to volume control
:
: It looks like the AES bits are set according to the selected device,
: since outputting PCM data via device 1 will not work (silence).
:
: Currently only the device 0 is shown via the "iec958" alias, and the
: second device is not accessible via hinted aliases.
:
: Simply provide access to both of these devices via the "iec958" alias.
:
: Reported-by: touc @ XBMC forum
: - ICE1712: add surround71 pcm definition
:
: The M-Audio Delta 1010 card has 7.1 analog output, but no ready-made pcm
: definition to use it.
:
: Reported-and-tested-by: Matt Zagrabelny <mzagrabe@d.umn.edu>
===Documentation===
: - doc: fix cross-compiling example
:
: Simplest way to configure cross-compilation with configure
: script is to pass '--host' option.
: Passing just '--target' doesn't work.
:
===Dynamic Loader helpers===
: - dlmisc: Remove unused label
:
: Fix a compile warning
: dlmisc.c:329:2: warning: label 'unlock' defined but not used [-Wunused-label]
:
: - snd_dlsym: only do versioning checks if built --with-versioning
:
: a combination of some of the following garbage collecting LD/CFLAGS
: -Os -g0 -fdata-sections -ffunction-sections -s -Wl,--gc-sections
: -fno-unwind-tables -fno-asynchronous-unwind-tables
: causes the symbol versioning marker symbols to be removed from BSS
: since they're otherwise unreferenced. this causes dlsym failing to
: find them which results in runtime breakage:
:
: $ alsamixer
: ALSA lib dlmisc.c:142:(snd_dlsym_verify) unable to verify version for symbol snd_config_hook_load
: ALSA lib conf.c:3328:(snd_config_hooks_call) symbol snd_config_hook_load is not defined inside (null)
: ALSA lib conf.c:3788:(snd_config_update_r) hooks failed, removing configuration
: cannot open mixer: No such device or address
:
: correct DSO:
: $ objdump -T libasound.so.2.strip | grep _snd_config_hook_load_dlsym_config_hook_001
: 001196bc g DO .bss 00000001 _snd_config_hook_load_dlsym_config_hook_001
:
: incorrect DSO:
: $ objdump -T libs/libasound.so.2 | grep _snd_config_hook_load_dlsym_config_hook_001
: 00000000 g DO *ABS* 00000001 _snd_config_hook_load_dlsym_config_hook_001
:
: since alsa was built with --without-versioning, doing those versioning
: checks at all is unnecessary and harmful and thus now disabled in this case.
:
===Filename helpers===
: - snd_user_file: fix memory leak
:
: Call wordfree if and only if wordfree returns zero or WRDE_NOSPACE
:
===Kernel Headers===
: - hwdep: add OXFW driver support
:
: Linux 3.19 newly support this driver. By hardware dependent interface,
: userspace applications can get hardware information, lock/unlock kernel
: streaming and receive lock status event.
:
: - pcm: Fix DSD sample format endianess and add big-endian format
:
: This patch adds big-endian DSD sample format and fixes return value of DSD
: formats for snd_pcm_format_little_endian().
:
: - pcm: add new 32-bit DSD sample format
:
: Add the new DSD_U32_LE sample format to alsa-lib.
:
: NB include/pcm.h and include/sound/asound.h are updated so a new sync with the
: kernel headers is not needed
:
: - Sync include/sound/asound.h with 3.17-rc1 kernel
:
: - pcm: Fix DSD formats userland usability
:
: Support for DSD sample formats has been added a while ago. This patch makes
: those sample formats beter usable from userland (e.g. aplay).
:
: [These implementation details have been forgotten in the previous DSD
: support patch -- tiwai]
:
: - pcm: Fill sw_params proto field
:
: Fill the new proto field introduced to sw_params with the current PCM
: protocol version. This makes tstamp_type evaluated properly in the
: kernel.
:
: - Add timestamp type to sw_params (internal only)
:
: This patch is just the udpate of sound/asound.h taken from the kernel
: commit. The API changes and PCM structure changes will follow after
: this.
:
: - pcm: Provide a CLOCK_MONOTONIC_RAW timestamp type
:
: For applications which need to synchronise with external timebases such
: as broadcast TV applications the kernel monotonic time is not optimal as
: it includes adjustments from NTP and so may still include discontinuities
: due to that. A raw monotonic time which does not include any adjustments
: is available in the kernel from getrawmonotonic() so provide userspace with
: a new timestamp type SNDRV_PCM_TSTAMP_TYPE_MONOTONIC_RAW which provides
: timestamps based on this as an option.
:
: Reported-by: Daniel Thompson <daniel.thompson@linaro.org>
===Simple Abstraction Mixer Modules===
: - sbase: fixed missing free
:
===Socket helpers===
: - Remove unused hostname resolution in shm plugins and aserver
:
: PCM and control shm plugins and aserver have some codes to resolve the
: host address and check whether it's a local host although the given
: address is never used. In addition, the code contains gethostbyname()
: that is known to be obsoleted. So, let's get rid of all these unused
: codes.
:
: The host configuration item is still accepted (but just ignored) for
: keeping the compatibility.
:
: - socket: missing socket close
:
===Test/Example code===
: - test/audio_time: Set timestamp type explicitly
:
==alsa-utils==
===Core===
: - Release v1.0.29
:
: - configure: allow contitional compilation of alsaucm
:
: If alsa-lib have been compiled with --disable-ucm, alsaucm can't be built.
: Detection is dynamic, no configure command line option is available for now.
:
: - Add missing alsa-info entry to the root Makefile.am
:
: - Add alsa-info.sh to alsa-utils repo
:
: Copied the latest version (0.4.63) from alsa-driver repo.
:
===ALSA Control (alsactl)===
: - alsactl/init: Add "Line Out" to list of outputs to initialize
:
: - alsactl/init: Change the "basic rules" description
:
: We now enable more outputs than just the main speaker, so update
: the basic rules to reflect the actual situation.
:
: - alsactl: add missing state_unlock() call
: - alsactl: coverity - missing_va_end – va_end was not called for "ap"
: - monitor: fix clang warning - Declared variable-length array (VLA) has zero size
: - alsactl: aded missing monitor() prototype
: - alsactl: Fix the file locking routines (for the state management)
: - alsactl: save state - do not call rename for stdio
:
===Speaker Test===
: - speaker-text: fix simple signess assignment warning
: - speaker-test: Add missing draining at the end
:
: Without the call of snd_pcm_drain() the pending data on the buffer
: might be discarded, which results in the abort of playback sound in
: the middle. Let's fix it.
:
: Reported-and-tested-by: Jarkko Nikula <jarkko.nikula@linux.intel.com>
===alsa-info.sh===
: - alsa-info.sh: add script to EXTRA_DIST (automake)
: - alsa-info: Refactor "withall" logic
:
: Previously, using --output, --no-upload, --upload and --pastebin
: switches implied the withall switch.
:
: A more intuitive logic would be that --with-all is disabled if you
: use another --with* switch, such as --withdmesg, and only then.
:
: Also update script version to reflect the behaviour change.
:
: - alsa-info: Make sure all full script is run even with "output" option
:
: For some reason, when the --output option is used, less information
: is included compared to when no options are used. This is unexpected.
:
: Fix this by running "withall" also when the output option is used.
:
: - Add alsa-info.sh to alsa-utils repo
:
: Copied the latest version (0.4.63) from alsa-driver repo.
:
===alsamixer===
: - alsamixer: include missing mixer_controls.h
===amixer===
: - amixer: Parse the value more strictly
:
: So far amixer allows some unexpected suffix and assumes as a raw
: absolute value without returning an error. This is rather dangerous,
: e.g. user might not notice that a completely wrong value was set when
: the command line included a typo.
:
: This patch makes the parser a bit more strict: it doesn't allow any
: longer invalid suffixes, instead either returns an error or skips the
: invalid value, depending on the operation mode.
:
: - amixer: Make "dB" case-insensitive in set commands
:
: We don't have to be necessarily too strict about case-sensitivity of
: "dB" suffix used in set commands.
:
===aplay/arecord===
: - Revert "aplay: fix pcm_read() return value"
:
: This reverts commit 8aa13eec80eac312e4b99423909387660fb99b8f.
:
: The semantics for pcm_read() and pcm_readv() was changed, but the
: callers expect the exact frame count as requested. It's possible
: to fix callers, but the fix is more complicated than to revert the
: change. Note that '-d' processing was broken in some cases.
:
: Note: The reverted commit allows that the return value might be
: greater than requested (see the first condition in read routines).
==alsa-tools==
===Core===
: - Release v1.0.29
:
: - Add a small "hdajacksensetest" helper

===HDA Jack Retask===
: - hdajackretask: Add dock hp/mic/line to simple options
:
: This allows for simpler setting of dock headphone, dock mic,
: dock line out and dock line in.
:
: Also improve detection a bit so that an existing dock headphone
: shows up as such and not as regular headphone.
:
: - hdajackretask: Add "hints" functionality
:
: The kernel driver has some hints you can send to it that changes
: parser behaviour. This patch exposes that functionality to the user.
:
: (This patch also includes minor fixes for documentation, GTK warnings
: and whitespace.)

===HDA Jack Sense Test===
: - Add a small "hdajacksensetest" helper
:
: I previously had a small python script doing the same thing,
: but it depended on hda-analyzer, which always breaks when something
: new is added to the codec proc file.

===ld10k1 (EMU10K1+ DSP Code Loader)===
: - ld10k1: Fix missing parentheses for functions
:
: The commit a1728250 removes bash-specific "function" but the necessary
: parentheses are missing.

===AudioScience ASIHPI Firmware===
: - asihpi: remove removed dsp2400.bin from Makefile.am
: - asihpi: Update firmware to version 4.14
:
: Also remove the superfluous file (dsp2400.bin) which was added
: mistakenly.

===A52 Output plugin===
: - a52: Ignore start request if we're already running
:
: When trying to start a PCM that's already running, the result is EBADFD.
: We might have implicitly started the buffer by filling it up,
: so just ignore this request if we're already running.

===Jack PCM plugin===
: - jack: Restore PID to jack client name when not specified explicitly
:
: Commit 14190cd8 added a facility to explicitly name Jack clients with
: a 'name' option, but did so in a way that was not fully
: backwards-compatible with older versions of the alsa-plugins. There
: were two issues:
:
: 1. Re-using the magical "name" variable, which comes preloaded with
: the name of the PCM
:
: 2. The code assumed snd_config_get_string sets a variable to NULL if
: the config entry does not exist. Instead, this function leaves the
: variable unchanged.
:
: The result of these two errors meant that the PCM name would be
: treated as if it were a user-defined name, and the old code which
: embedded the PID would never be run
:
: This code uses a completely new variable to store the explicitly-set
: client name, so that the two code paths no longer collide.
