** Description changed:
+ [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.
