Hey,
As I was trying to test PulseAudio HDMI LPE audio support fixes, I
realised that the internal sound card of my Surface 3 wasn't working
anymore, using the same user-space configuration.
Looks like detection of the device regressed between 2 versions. Does
this look familiar to anyone, or should I start bisecting? (which will
take me absolutely ages, as the CPU is anemic on that machine)
Yes this looks familiar unfortunately. Surface has a BIOS quirk iirc,
and there are reports of broken audio on other platforms that have a
similar quirk, see
https://bugzilla.kernel.org/show_bug.cgi?id=96691 where the patch
7827d66946ad3af734ed46d1d68c23fa6974595c is flagged as being the issue.
I tried providing a patch for what I think is the problem, but the
reports from users were inconsistent and I don't have access to the
hardware.
If you could try both the revert and the suggested fix (separately) it'd
help a great deal
