Public bug reported:
Version: Ubuntu 20.04.01
My Tongfang PF5NU1G's internal microphone used to work on an older
kernel version (5.4) but since I've upgraded the kernel to 5.8+ due to
better support for AMD Renoir (Ryzen 7 4800H + Radeon Vega 8 graphics),
the internal mic stopped working.
I have also tried to use kernel version 5.6, but has the same problem.
The mic is selected in the settings menu as: Digital Microphone-Family
17h(Models 10h-1fh) HD Audio Controller
When i record audio with the default input source selected in Audacity,
it records a small static-like sound. The microphone does not detect any
input it seems.
Thanks in advance!
