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
