Also try, if you still have pulseaudio enabled, the alsamixer command as 
below.

alsamixer -D hw:0

This will show all controls for your soundcard. I have no experience using USB 
headsets, but you may find that some slider needs to be pushed up to get 
sounds out of your headset. The F4 key will switch alsamixer to capture 
settings, and have found that for my TV card on one distro, I have to have 
some sliders pushed up to get sounds out from my TV card on the capture view 
of alsamixer. Just some thoughts, as I'm running out of suggestions.

Nigel.
