Comment 10 for bug 1860697

I'm running 5.4.0-18 from focal-proposed and have installed the sof firmware from this pull request:

https://lists.ubuntu.com/archives/kernel-team/2020-March/108035.html

With this it looks like the sof driver is being used. Speaker output works, though the volume seems very low (which has always been the case under Linux on this laptop, so maybe that's normal?). The only input device listed is sof-hda-dsp, which does not appear to be picking up any sound.
