I have just verified that guvcview is not working on my Fedora 34 Gnome
I suspect this is a pipewire issue, but so far I have found nothing
This sounds similar:
however, although my audio sources are suspended, they show up as
running when guvcview is recording. I tried to make changes to alsa-
monitor.config to disable suspend, but that did not seem to work.
I'll continue to investigate and/or submit a ticket somewhere if I can
debug this further.

This is a strange problem. I record a video with audio using

if I playback a video I created with guvcview under Fedora 33 the
audio is fine.
guvcview with every combination of audio codec and audio device (both
from my web cam and from my MOTU audio interface.)
gucview audio level bars (overlaid on video display) indicate audio
is being received during recording
Playback: VLC and Dolphin. If I play an older Fedora 33 video vlc
shows up in carla correctly, if I then try to play a new Fedora 34
video it disappears.
Log messages: I'm getting lots of these:
