I have a usb microphone and it’s detected by ALSA and works properly with PulseAudio, but when I use pipewire it stops working.

This is the output of arecord -l :

can you check:
wpctl status and see what’s listed for the microphone?

Thanks

Thanks for replying.

Here is the output of wpctl status

Does it make any difference if you remove ~/.local/state/wireplumber ?

This will reset what ever you have set as default for sound.

I’ve removed ~/.local/state/wireplumber folder, but the microphone still doesn’t work. This the result of wpctl status :

I should mention that the microphone works with arecord and I can record my voice by running the following command :

[ayman@fedora ~]$ arecord --duration=10 --format=dat --device=hw:2,0 test.wav -c1
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

Can you check and see if it’s selecting a valid profile?

The simplest way will likely be to use pavucontrol.

You could also use pactl set-card-profile "I used tab complete to find the device & profile"

Is there any other solution?

Does changing the profile make any difference or is that the only one available?

You may want to compare the output of:
pactl list cards
pactl list sources

with pulse working
and pipewire not working.

Did this work on older kernels?

This may just be a bug in pipewire.
