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

Comment 5 mike 2021-06-02 13:40:57 UTC
More Info 
Microphone works on another laptop with following lspci output
<pre>00:1b.0 Audio device: Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Series High Definition Audio Controller (rev 21)</pre>
The laptop where it doesnt work is
00:1b.0 Audio device: Intel Corporation Atom Processor Z36xxx/Z37xxx Series High Definition Audio Controller (rev 0e)

Tried with new user and as root, no difference.

No errors, just no input

If I disable pipewire using
sudo dnf swap --allowerasing pulseaudio pipewire-pulseaudio

it all works, so definitely appears to be pipwire specific

This message is a reminder that Fedora Linux 34 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 34 on 2022-06-07.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '34'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 34 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 7 Ben Cotton 2022-06-08 06:31:49 UTC
Fedora Linux 34 entered end-of-life (EOL) status on 2022-06-07.

Fedora Linux 34 is no longer maintained, which means that it
will not receive any further security or bug fix updates. As a result we
are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release.

Thank you for reporting this bug and we are sorry it could not be fixed.
