description |
This bug is for tracking purpose. |
This patchset was backported from mainline alsa-utils 1.2.3, and
groovy already integrated alsa-utils 1.2.3, there is no need to SRU
this patchset to groovy, so only for focal.
[Impact]
We enabled 2 Dell soundwire audio machines, these machines depend on
ucm to make the audio work, and in the ucm, the _boot section defined
some amixers values for the 1st booting, these amixer values should
be set to audio driver at the 1st booting, otherwise the whole audio
doesn't work.
[Fix]
Backport some patches from mainline v1.2.3, these patches make the
alsactl support _boot section in the ucm, then the systemd will call
alsactl init after booting, the alsactl init will setting all amixers
defined in the _boot section of ucm.
[Test Case]
On the Dell soundwire audio machines, After booting up, run 'amixer
contents | less' to check all amixer values defined in the _boot
section of ucm, all values read from driver are same as the ones in
the ucm, test speaker/microphone/headset, all work well.
[Regression Risk]
This could introduce failure on runing 'alsactl init' for some machines,
then the amixers will not be initialized correctly, users will experience
all audio can't work like speaker doesn't output sound or microphone can't
record sound. But this regression possibility is very low, since We have
tested it both on soundwire machines and non-soundwire machines, all worked
well. |
