- backport GIT PATCHES:

Browse Source 
* A few alsactl init fix patches:
  * amixer control-id parse fix
  * new aloop utility
  * robusitfy speaker-test 
  * misc clean up, translation updates
- Use systemd for openSUSE 11.4
- Put udev rules into this package instead of alsa.rpm

From bee994f509e6829647aa68fd276f5e8821d15445 Mon Sep 17 00:00:00 2001
From: Jaroslav Kysela <perex@perex.cz>
Date: Mon, 11 Oct 2010 10:24:14 +0200
Subject: [PATCH 25/38] alsaloop: Fixes and added --workaround option
- added workaround for alsa-lib (pthread configuration parsing issue) -
the workaround must be activated manually using ('--workaround serialopen')
- fixed avail_min initialization (caused high CPU usage or xruns)
- fixed shared buffer initialization (both capture and playback buffers
must have equal number of samples in this config)

From de7c3eff0e371ce155403bbcdcf81ee79266fa0f Mon Sep 17 00:00:00 2001

Subject: [PATCH 37/38] alsactl: systemd and udev hookup
Add minimal systemd and udev support to alsactl so that mixer settings
are restored at boot, when sound cards are plugged in and saved on
shutdown.
This is similar to existing udev/init script solutions in various
distributions.
Note that alsactl is called both synchronously from the udev rules as
well as asynchronously at boot. This is intended, and to ensure two
things:
- At boot the asound.state file might not be readable, since it resides
on a different file system. That means exclusively restoring sound card
settings from udev rules will no suffice, since if the rule is
executed at early boot (for example within udev settle) then the file
will no be readable and cannot be restored.
- We need to ensure that applications monitoring sound cards coming and
going (such as PA) must not get these events before the mixer settings
have been restored. That means the mixer settings must be restored
synchronously withing the udev rules, before the events are passed on
to the apps.
That basically means we need to restore the settings once in udev, to
deal with sound cards becoming available during runtime. And once in
early boot to deal with coldplugged soundcards whose data files might
not have been available at time of plugging. Hence we call alsactl
twice: one from the udev rule, and once from he systemd unit file.

Subject: [PATCH 38/38] alsactl: Move asound.state location to /var/lib/alsa
.... and add configure switch for it.
/etc might be on a read-only partition which is not suitable for dynamic
data such as the mixer settings. Hence move the location of asound.state
to /var/lib.
This is based on a patch from Ubuntu/Debian which hardcoded the pah in
/var/lib.

Subject: [PATCH] configure.in: Fix variable name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fix variable name for --with-asound-state-dir as currently we have
to pass --with-ASOUND_STATE_DIR= which is wrong and inconsistent with
the other switches.
