Hi Don.

The above is fair enough. If you had more than one USB audio device plugged 
in, I'd expect to see a card listed, when running, cat /proc/asound/cards, 
when the headset is not plugged in.

Try opening alsamixer as user, on Gnomes terminal, or KDE's Konsole, as below.
alsamixer -D hw:1

This should show any controls available for your Cmedia USB headset. Something 
may be muted (M key toggles mute/unmute), or perhaps there is a slider that 
needs to be pushed up.

Pulseaudio, which has been the default soundserver since F8, can be a pain in 
the neck, and sometimes causes problems with various audio apps. You can 
disable it by simply removing the package, alsa-plugins-pulseaudio, then your 
audio apps will use alsa directly. You can also re-enable it later if you 
wish, by just re-installing the package.

yum remove alsa-plugins-pulseaudio

If you're using KDE, as I am, removing the above package, will also remove 
kde-settings-pulseaudio, so when re-installing alsa-plugins-pulseaudio, you 
will also have to re-install kde-settings-pulseaudio.

All the best.

Nigel.
