When they gave me a USB camera/mic for meetings for work (thanks Covid),
I pretty quickly learned that trying to run this device under ALSA was
not for me. That's when I finally bit the bullet and installed Pulse Audio.
Yours also appears to be a USB camera/mic (based on 1 minute with Google),
so my advice may fit.
The major problem with ALSA (for me, at least) is that it's damned near
impossible to find any documentation on how to tell the computer, "OK,
look, I've got two audio devices now. I'd like you to use this one for
output, because it's where my speakers are plugged in. I'd like you to
use that one for input, because it's a microphone." You'd think this
would be pretty basic and simple, but it's not.
Pulse, on the other hand, just works. At least for me.
But there's a trick to it. You have to... NOT start Pulse Audio yourself.
Don't put anything in your login or session-starting files. Nothing. If
you do, it won't work properly, and you'll waste a whole lot of time.
You have to let it start itself "on demand". That's it. That's the trick.
