Description mike 2021-05-04 10:59:27 UTC
After upgrading to fedora 34 no input is obtained from internal microphone.
Using gnome-sound-recorder as a test.

No sound is recorded and pavucontrl shows no input from microphone

The microphone appears in audiomixer (pavucontrol I assume)
All modules seem to be loaded and playback is fine

the only error message I can see is from dmesg -T
traps: gnome-sound-rec[2335] trap int3 ip:7f9b4652df7f sp:7ffdf71ddc70 error:0 in libglib-2.0.so.0.6800.1[7f9b464ef000+90000]

If a cheap microphone is plugged in I get sound recorded, but nothing from internal mic

Well now confused.
After following instructions to update using testing, everything worked.

However after rebooting and doing sudo dnf update, following todays message, I'm back to no sound being recorded
