Closes: https://github.com/alsa-project/alsa-plugins/pull/48</code>
- jack: use program_invocation_short_name
- jack: implement pcm operation sw_params
<code>
Alsa-lib commit 88e4ae27 introduced a dynamic recalculation of the avail_min
value on the underlaying slave devices.
This updated avail_min value is not reaching the alsa-jack plugin due to lack
of the sw_params operation.
This patch adds this missing operation to correctly apply an updated avail_min
setting during runtime.</code>

<code>
As libsamplerate itself was already relicensed to 2-Clause BSD
license, there is no need for restriction of GPL license for
samplerate plugin, too.

Let's switch to LGPL-only for relaxing the use.

Luckily, I am the sole author of this piece of code, so it should be
no legal problem for immediate relicensing.

===Core===
- Release v1.2.12
- GitHub Actions: Use actions/checkout@v4
- pcm: plug - add automatic conversion for iec958 subframe samples
<code>
As Pavel noted, a possibility to automatically convert standard
linear samples to iec958 subframe format would be handy for latest
Raspberry HDMI driver.

===PCM API===
- pcm: extend doc for snd_pcm_hw_params_get_sbits()
<code>
Try to explain more the output value and its relation between
format and sample bits defined by the format.

Link: https://github.com/larsimmisch/pyalsaaudio/pull/146</code>
- pcm: clarify and fix default sbits (msbits) value for all formats
<code>
As described in the kernel patch (link bellow), the significant (resolution)
bits should be related to the usable sample bits not the physical sample bits.

- pcm: ladspa - Skip missing ladspa directories
<code>
Closes: https://github.com/alsa-project/alsa-lib/pull/385</code>
- pcm: snd_pcm_(physical_)format_width() - change documentation
<code>
The word "nominal" is not so correct here. Use similar
wording as we use in the kernel space (the bit-width of the format).

===Topology API===
- topology: correct version script path
<code>
contrary to libasound, version script for libatopology is a regular
source file. while it's often the case that $(builddir) and $(srcdir)
point to the same directory, they don't always have to. therefore path
needs to point explicitly to $(srcdir) for Versions script in topology

Closes: https://github.com/alsa-project/alsa-lib/pull/383</code>

<code>
Use the appropriate variable for access/eaccess call.</code>
- ucm: fix Path condition - substitute Path and Mode fields
<code>
The Path and Mode fields should be also substituted for
the runtime evaluation. See Fixes.</code>
===Async helpers===
- async: snd_async_del_handler - move clear signal using sigaction as last
<code>
Improve the shutdown order for the asynchronous users. There may be
unhandled signals, because the signal is reset before signal deactivation
using fnctl (O_ASYNC).

Closes: https://github.com/alsa-project/alsa-lib/issues/394</code>
===Configuration===
- conf: aliases: hdmi: Include unconditionally the
<code>
The hdmi.conf contains the high level macro to be used by cards to create
the hdmi: device.
Instead of including it in different config files, include it in the main
aliases.conf and remove it's inclusion by other config files.

This change is needed to add support for the hdmi: device mapping via UCM.

Closes: https://github.com/alsa-project/alsa-lib/pull/393
Suggested-by: Jaroslav Kysela <perex@perex.cz></code>
- conf: USB-Audio: Add Corsair HS60 Pro to the IEC958 blacklist
<code>
This device is just an external USB soundcard with a female 3.5mm jack
for a headset, no S/PDIF | IEC958 connector. Add it to the blacklist to
prevent it being opened.

Link: https://lore.kernel.org/alsa-devel/ZeWGbxZIc7AF96h0@m.b4.vu/</code>
- conf: USB-Audio: Add more Scarlett devices to the IEC958 blacklist
<code>
The Scarlett Solo and 2i2 don't have S/PDIF outputs.

===alsa-info.sh===
- alsa-info.sh: log SoundWire devices reported in ACPI
<code>
Track SoundWire devices reported in ACPI, this will help detect
missing or invalid configurations.

For now we only filter information from Realtek, Cirrus Logic and TI,
based on the manufacturer ID of their devices.

Example log for the classic RT711/RT1316x2/RT714 configuration.

!!ACPI SoundWire Device Status Information
!!---------------

Realtek 0x000030025d071101
Realtek 0x000331025d131601
Realtek 0x000230025d131601
Realtek 0x000130025d071401

As noted by reviewers, the script reports everything exposed in
ACPI. In practice some of the devices listed may not be physically
populated in hardware, or be listed as attached on a link that's
disabled by the manager. The drivers can cope with this case, it's not
technically an error.

Closes: https://github.com/alsa-project/alsa-utils/pull/264</code>
===alsamixer===
- alsamixer: fix calculation in set_normalized_volume (overflow)
<code>
Lowering volume below 0 causes overflow spike to 100% volume (volume goes
below 0 and back to 100 repeatedly). 0 overflows past infinity when holding
down z,x,c.

> value = lrint_dir(6000.0 * log10(volume), dir) + max;
(where volume = 0 , and dir = -1 . min = -9999999 , and max = -6)
> log10(0) is negative infinity = error</code>
===alsatplg (topology)===
- topology: nhlt: Intel: Improve all error prints
<code>
Many error prints had obsolete function name written in them, use
__func__ everywhere and add problematic value to the print if its
available.

Closes: https://github.com/alsa-project/alsa-utils/pull/254</code>
- topology: nhlt: Intel: Clear DMIC BFTH bits for version
<code>
The former Burst Fifo ThresHold bits 20-23 in output register are
specified as reserved bits starting from driver version 4.

Closes: https://github.com/alsa-project/alsa-utils/pull/254</code>
- topology: nhlt: Intel: Add check for DMIC version
<code>
Error if the version passed from topology is not known. Also fix the
dmic_set_params() error prints for to show the correct function name.

Closes: https://github.com/alsa-project/alsa-utils/pull/254</code>
===aplay/arecord===
- aplay: fix S24_LE wav header
<code>
S24_LE is 32 bits in width storing 24 bits of data and 8 bits of padding
So wav header needs to be 32 bits not 24

<code>
Add the dump functions for UMP Type 0 (Utility) and Type 1 (System)
messages.</code>
===aseqsend===

==alsa-ucm-conf==
===Configuration===
- sof-soundwire: fix missing MultiCodec1 initialization and Empty condition
- UCM2: Intel: sof-hda-dsp: Control SOF processing from UCM
<code>
This patch adds to Intel/sof-hda-dsp/HiFi.conf inclusion of
HiFi-sof.conf that by redefine of headphone and speaker handling
adds to UCM control of DRC and EQ SOF processing components.

The modified setting are applied in case of SOF processing
components' controls are detected. There is no change to operation
if no controls are present e.g. with legacy SOF topology.

If DRC control is found, it is assumed that also FIR and IIR
also exist. If there is no DRC but FIR is found, then it is assumed
that IIR also exists. This matches SOF FW builds for IPC3 (FIR, IIR)
and IPC4 (DRC, FIR, IIR). The controls names are different in IPC3
and IPC4 topologies. Also the configuration blobs differ.

The speaker mode is by default set up with 100 Hz high-pass IIR. The
DRC is set to a default speaker setting that boosts playback loudness.
The FIR is bypassed.

In the headphone mode all the processing is set to bypass and DRC
switch is set off.

The processing can be customized for products with UCM scripts placed
into blobs/sof/product_configs. The file path should be
<sys_vendor>/<product_name>.conf from DMI ID. An user configuration can
be similarly placed into blobs/sof/user_configs directory to e.g. avoid
it being overwritten by distribution.

Closes: https://github.com/alsa-project/alsa-ucm-conf/pull/419</code>
- UCM2: SOF: Add example blobs customization for AAEON
<code>
This example shows how to define IIR, FIR, and DRC processing for
speaker and headphone endpoints.

Closes: https://github.com/alsa-project/alsa-ucm-conf/pull/419</code>
- UCM2: Add sample SOF processing configuration blobs
<code>
The example set contains passthrough configuration blobs with SOF IPC3
and IPC4 headers for DRC, FIR, and IIR. A few high-pass configurations
are added for IIR to be used e.g. for speakers. A DRC blob is added
that can be used to boost speaker playback loudness.

The blobs are all in binary format.

Closes: https://github.com/alsa-project/alsa-ucm-conf/pull/419</code>
- codecs: qcom-lpass/tx-macro: Move TX1 MODE ctrl to
<code>
The tx-macro is a common interface for WCD937x and wcd938x and
also the TX1 MODE setting is not applicable for WCD937x codec.

The TX1 MODE mixer controller is derived in WCD938x codec driver,
So move TX1 MODE mixer control to wcd938x.

- ucm2: sof-soundwire: Create ALSA config file for hdmi:
<code>
If the HDMI PCM index (3-5) is found in iec61937-pcm list of the card's
components list then use the HdmiPCM/HdmiPCMSave macros to create the
configuration file.

The PCMs that will be created are:
aplay -L | grep hdmi

hdmi:CARD=sofsoundwire,DEV=0
hdmi:CARD=sofsoundwire,DEV=1
hdmi:CARD=sofsoundwire,DEV=2

Audio servers (Pulseaudio, Pipewrire) or applications then can use these for
bytestream passthrough, for example:
mplayer -ao alsa:device=hdmi=sofsoundwire,DEV=0 -ac hwdts <video with dts>

- ucm2: common: pcm: Add hdmi.conf to handle the creation
<code>
User space expect to see hdmi: PCM devices to be able to use bytestream
passthrough.

The common/pcm/hdmi.conf provides two macros:
HdmiPCM: to generate an ALSA conf section for an hdmi: PCM device
HdmiPCMSave: to save the generated config

Example of use (sof-hda-dsp card with hardware HDMI PCMs: 3-5):
Macro.0.HdmiPCM { Device 3 Index 0 }
Macro.1.HdmiPCM { Device 4 Index 1 }
Macro.2.HdmiPCM { Device 5 Index 2 }
Macro.3.HdmiPCMSave { }

Besides the improvement by using analog volume control, it also makes
volume levels normal instead of insanely high levels reached by this
digital mixer.

- ucm2: MediaTek: mt8195-sof: Add support for Tomato RT5682s
<code>
A later revision of the MT8195 Cherry Tomato Chromebook (Acer Chromebook
Spin 513 CP513-2H, Revision 3 and 4) are using the RT5682s codec instead
of RT5682i.

The differences are only about a couple of missing switches, where the
'i' variant had a switch for the L/R Headphone output and a configurable
DAC L/R Mux, while the 's' one misses the mux control and solely relies
on the main Headphone Switch.

- sof-soundwire: rt1316/rt1318 - fix channel selection for one amp
<code>
Like in commit 9e29f9e27f4e27dce40d8d6803031bb4f7be3c48, use L-R
channel selection when single amp is present.</code>
- sof-soundwire: rt1308: Fix single amp configuration
<code>
If the device have single rt1308 amp then the codec's Channel Select should
be set to "LR" and not to "LL". "LL" is only valid if we have 2 amps, in
that case one is the Left and the other is the Right channel.

This fixes for example Dell Latitude 9520 which only played on the Left
speaker, Right is silent.
