[Trisquel-users] getting USB headset to work

[me]

I have a Logitech H390 USB headset that is detected as such, but in the Sound  
settings (default app), it is marked as "Disabled", and I don't see an option  
to enable it so I can route sound input/output to it instead of my onboard  
sound card.

How can I do this? Also, I searched the web for this issue first, but didn't  
find anything that helped. Tried installing various pulseaudio UIs like  
pavucontrol, paman, and others, and I also tried to play with alsamixer to  
fix it, to no avail.

Thanks,
Brent
