No Microphone input on fedora 34 (pipewire)

[Mike Martin via users <users@xxxxxxxxxxxxxxxxxxxxxxx>]

Since installing fedora 34 I have 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]

But zero input from mic

If I plug in a cheap microphone it works, so something weird is happening

Any ideas
