All,
I am planning to use GnomeMeeting as a replacement for NetMeeting. I
have been successful in getting voice activated on GnomeMeeting.
My problem... my counterpart who also uses Gnomemeeting is able to hear
me but not reply. Same way, I am unable to hear him. Perhaps this is a
problem with Duplexing, that is, my audio-output gets disabled when I
use the mic.
I have installed the latest rc2 ALSA drivers but sound is status quo.
Any leads from Indo-Linuxers who have been able to overcome this problem
is welcome and appreciated.
Best regards
Prakash
