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.
