Comment 26 for bug 1845678

Hi,

I wanted to give a bit of feedback after a few days using the laptop with kernel 43 and the experimental libasound packages from Hui's ppa.

As far as I can tell, the microphone works flawlessly.
Sound output to speakers and HDMI works too. With one notable drawback : the internal speaker volume, even when maxed out in alsamixer and gnome settings is very weak, much weaker than when using the snd_hda driver. I think this is related to https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1859754/comments/28 and one should be aware of it before switching to sof.

Plugging a BT headset correctly switches output to the headset and joining a google meet visio conference in firefox switches the microphone too.

As reported in https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1859754/comments/86 the chrome snap seems to do something different from firefox ending up in crashing the BT headset when joining a google meet visio.
