Same problem here.
SUSE Linux 10.0 / ALSA sound system
Plantronics USB headset works when tested with gnomemeeting ( voice is recorded and played back ).
But Skype refuses to work with the headset. No sound at all...
Searched several days on the web. Seems like this is a common problem, but can 't find a solution.
Seems like a common Fedora / SUSE problem
Anyone an idea ?
