For me applying patch 4961167bf7482944ca09a6f71263b9e47f949851 on top of 5.10.12 fixes audio, but the above quoted patch applied to 5.10.12 does NOT fix audio. What I mean by fixes:
Audio works normally on 5.4.94, and on 5.10.12 with patch 4961167 applied.
I hear no audio from the laptop speakers on 5.10.12 and 5.10.12 with the above quoted patch applied. Opening pavucontrol shows a graphical response in the meter, but no audio is heard from the speakers. I did not test plugging in headphones and did not test audio over HDMI.

I have a System76 Gazelle Pro 7 (gazp7).

Apologies if this is noise. I haven't been able to find if 4961167bf7482944ca09a6f71263b9e47f949851 is queued up for the next stable release of 5.10.
