Changelog between 1.0.27 and 1.0.27.1 releases

alsa-lib

Core

- Release v1.0.27.1

- Remove an obsolete macro in configure.in

Replaced AM_CONFIG_HEADER with AC_CONFIG_HEADERS

lano1106@whippet2 ~/dev/alsa-lib $ ./gitcompile

aclocal: warning: autoconf input should be named 'configure.ac', not 'configure.in'

configure.in:56: error: 'AM_CONFIG_HEADER': this macro is obsolete.

You should use the 'AC_CONFIG_HEADERS' macro instead.

/usr/share/aclocal-1.13/obsolete-err.m4:12: AM_CONFIG_HEADER is expanded from...

configure.in:56: the top level

autom4te: /usr/bin/m4 failed with exit status: 1

aclocal: error: echo failed with exit status: 1

- Add AM_MAINTAINER_MODE.

Add AM_MAINTAINER_MODE([enable]) to configure.in.

- conf/ucm: Set up for installation

- Add definition of __inline__ for non-GCC

- Use __inline__ for exported headers

Some programs are still using C90.

- bring pcm.h and pcm.c in sync with the kernel list

In particular, this adds definitions and descriptions for G.723 and

DSD types.

- pcm.c: fix indentation

RawMidi API

- Fix several spelling errors for “writable” and derivatives.

Sequencer API

- seqmid: restore sequencer address prefix match feature

Commit 19892334499e (seq: Fix for snd_seq_parse_address()) removed the

ability to match sequencer client names by any of by their prefixes in

an attempt to avoid wrong matches when one client name is the prefix of

another.

However, the prefix match feature was documented and actually used.

Allow prefixes to match, but only if there is no exact match.

ALSA Lisp

- Fix several spelling errors for “writable” and derivatives.

Configuration

- conf/ucm: DAISY-I2S: Set default filter mode for HiFi.

Default to music mode filter for the HiFi use case on the Samsung ARM

Chromebook. This mode is better at 44.1k and 48k audio than the

"Voice" setting.

- conf/ucm: Set up for installation

- conf/ucm: tegraalc5632: add UCM config from Ubuntu

- conf/ucm: SDP4430: add UCM config from Ubuntu

- conf/ucm: PandaBoardES: add UCM config from Ubuntu

- conf/ucm: PandaBoard: add UCM config from Ubuntu

- conf/ucm: DAISY-I2S: add Samsung ARM Chromebook UCM config from ChromeOS

- conf - Add Scarlett 2i2 USB to S/PDIF blacklist

The Scarlett 2i2 USB interface does not have any S/PDIF connections.

Dynamic Loader helpers

- Compile in the ALSA search path instead of relying on ld.so.conf.

The Ubuntu package currently uses ld.so.conf.d fragments to add

/usr/lib/alsa-lib and /usr/lib{32,64}/alsa-lib to the dlopen search path.

These don't *belong* on the global search path, and it becomes much more

problematic to put them there with the advent of multiarch because each

architecture then needs its own distinct config file to add the separate

path... which is then also put in the global library namespace. Instead,

let ALSA make use of the already defined ALSA_PLUGIN_DIR to look up

plugins.

- Fix doubly call of dlclose() in dlobj caching code

When multiple dlobj_cache items point to the same dlobj, dlclose() may

be called wrongly multiple times when these items are cleared, because

we manage the dlobj_cache list as a flat list. This results in a bad

segfault we've seen in openal-soft, for example.

For fixing this, we need the refcounting of dlobj itself. But, in

this case, we don't have to manage yet another list, since dlopen()

does a proper refcounting by itself. That is, we can just call always

dlopen() at each time a new function is assigned, and also call

dlclose() for each released dlobj_cache item at cleanup.

alsa-utils

Core

- Release v1.0.27.1

- Add AM_MAINTAINER_MODE([enable]) to configure.in.

ALSA Control (alsactl)

- alsactl: remove 90-alsa-restore.rules from the tar ball

- Fix a build failure due to a misused format string.

This fixes builds with -Werror=format-security.

- alsactl: sprintf to snprintf prevent buffer overflow

sprintf() is a bit dangerous unless you explicitly know your type size

and want to keep it in sync always. Its safer to just use snprintf() and

ensure your string doesn't overflow and is NULL terminated.

- alsactl: Fix the string size for the lock file contents

The string length is 10 characters + LF + '\0' = 12 characters.

- alsactl: Fix a typo in systemd alsa-restore.service
