Bug description:
[SRU Justification]
[Impact]
On some platforms with Cirrus CS8409 audio codec, DMIC volume default
value in kernel driver is 0, which follows no audio sound will be played
during installation and OOBE until being explicitly configured again via
GNOME Settings GUI or other methods.
[Fix]
Commit 527ff9550682 ("ALSA: hda/cirrus: Set Initial DMIC volume to -26
dB") currently landed in upstream tiwai/sound.git is required to address
this issue. It's a follow-up of commit 0e853a9c3937 ("ALSA: hda/cirrus:
Set Initial DMIC volume for Bullseye to -26 dB"), which is applied in
bug 1923557.
[Test Case]
Try to remove all the user space settings caches and reboot. The
detailed steps are:
# reboot to another system with access, e.g. livecd
livecd$ sudo mount /dev/nvme0n1p3 /mnt
livecd$ sudo rm /mnt/var/lib/alsa/asound.state
livecd$ sudo rm -rf /mnt/home/u/.config/pulse
livecd$ sudo reboot # reboot back
The original status is like:
$ amixer sget 'Internal Mic',0
Simple mixer control 'Internal Mic',0
Capabilities: cvolume cswitch
Capture channels: Front Left - Front Right
Limits: Capture 0 - 63
Front Left: Capture 0 [0%] [-51.00dB] [off]
Front Right: Capture 0 [0%] [-51.00dB] [off]
Expect 40% in the front left/right capture volumes.
$ amixer -c 1 sget 'Internal Mic',0
Simple mixer control 'Internal Mic',0
Capabilities: cvolume cswitch
Capture channels: Front Left - Front Right
Limits: Capture 0 - 63
Front Left: Capture 25 [40%] [-26.00dB] [on]
Front Right: Capture 25 [40%] [-26.00dB] [on]
[Where problems could occur]
This gives the default value of Cirrus CS8409 audio codec capture volume.
It was previously found on another platform, Bullseye, and fixed in bug
1923557, while latterly convinced being a common bug that should be
fixed without the quirk.
[Other Info]
By SRU we skipped a couple of refactoring changes in asound upstream
tree, so additional changes to the original patch are required to
backport. On v5.12 and on, say unstable, the fix can be cleanly
cherry-picked.
========== original bug report ==========
This is a similar bug to bug 1923557, which happens on Dell Bullseye. The
initial default input volume right after Ubuntu installation is set to 0% while
16% is expected.
