FYI, the 'solution' for this issue that is now in the kernel breaks
capturing screen+currrently playing audio with ffmpeg, for me at least,
on AMD Raven hardware.
I tried many things but could not achieve good audio capture that is
synchronised, not when capturing from Pulse anyway.
I'm guessing it's being in BATCH mode, and Pulse not operating with
tsched, that is the problem, not the rest of the patchwork.
Nonetheless I just wanted things to work as before without any doubt, so
I now have my kernel patched with the following (restoring 1022:15e3 to
use the parameter sets it used to before all this) and everything is
working fine now:

While I greatly appreciate the work on the microphone input crackling issue
(which I have experienced and been annoyed by myself over the years), i'm
concerned that the current solution should've been further tested and developed
before being mainlined.

Title:
Microphone distorted sound on ALC892/1220 on AMD chipsets
Status in Linux:
Confirmed
Status in linux package in Ubuntu:
Won't Fix
Status in pulseaudio package in Ubuntu:
Won't Fix
Bug description:
Not sure if I'll report this upstream but there is definitely an issue
with microphone recording on my desktop, this is not happening on my
laptop which has a different codec.
Already tried all workarounds possible, no luck. Only with my desktop
with this particular motherboard. No issues in Windows, the sound
recorded in there is distorted and has some static and robotic tone on
high-pitch.
