[Bug 1897934] Re: [SRU][Intel HDA] The initial sound level is set to zero (muted)

[Iain Lane]

I don't see the same problem on the Focal ISO - do we need to fix this
in Focal?

** Changed in: alsa-lib (Ubuntu Focal)

Title:
  [SRU][Intel HDA] The initial sound level is set to zero (muted)

Status in Release Notes for Ubuntu:
  New
Status in alsa-lib package in Ubuntu:
  Fix Committed
Status in alsa-lib source package in Focal:
  Incomplete
Status in alsa-lib source package in Groovy:
  Fix Committed

Bug description:
  [Impact]
  Fail to run '/usr/sbin/alsactl restore' on the HDA-Intel machines, this
  results in the failure on setting the init mixer values for HDA sound
  card, and users experience the mute of audio after installing the 20.10.  

  [Fix]
  Backport a patch from the latest alsa-lib (v1.2.3+)

  [Test]
  Without the patched alsa-lib, rm ~/.config/pulse/*;sudo rm /var/lib/alsa/*;
  sudo sh -c "echo b > /proc/sysrq-trigger", after booting up, the audio is
  muted.

  Install the patched alsa-lib, rm ~/.config/pulse/*;sudo rm /var/lib/alsa/*;
  sudo sh -c "echo b > /proc/sysrq-trigger", after booting up, the audio is
  not muted.

  [Regression Potential]
  This could make the ucm audio fail to initialize, but this possibility is
  very low, since this patch is from upstream, and I tested on a ucm based
  machine, the audio is good.

  
  On boot into the live session - or on first install the sound level is muted.

  I have to use GNOME Control Center - Sounds to change to an
  appropriate level.  Once changed the level chosen is correctly
  retained between reboots.

  This appears to be a regression from 20.04 where the sound level was
  set to - I guess - 80% on the live-session/first install
