Bug Description
The change of this SRU has been squashed to https:/
[Impact]
For the machines with sof audio driver, after we freshly install the ubuntu linux and plug a microphone or headset-mic to the audio jack, we can't record sound through them since the default input volume is 0, users need to adjust the input volume to non-zero manually, then could record sound successfully.
[Fix]
Backport 1 patch (https:/
[Test]
sudo rm /var/lib/alsa/*; rm ~/.config/pulse/*; alsactl init; reboot, plug a headset to the audio jack, use the headset-mic to record the sound, it could record successfully.
[Where problems will occur]
This SRU changes the Capture Switch and Capture Volume in the ucm, this could make the whole ucm can't be parsed if the syntax is not correct, then the whole audio will fail to work like audio jack can't detect plugin/plugout and the internal mic can't be found. But this regression possibility is very low since we already tested the change on lenovo and Dell machines, all worked well.
