I don't think so. My idea is that you are not using ALSA (but you are using it), or that perhaps your soundcard is natively not FUll - Duplex. I don't
know. Have I already asked you to test cat /dev/dsp > /dev/dsp ?

Not really, it should work with KDE too, GnomeMeeting has plenty of KDE users.

If mixer is set to 0, it means that the volume is 0.
But I wonder, what happens if you change the volumes with GM, then exit and
restart it ? Are the volume set to 0 again or not ?

You can see in the history log of gnomemeeting (View->History) that two
sound channels are used : Transmitting and Receiving.
If you only see one of them, or not at all, then there will be no sound
cause no common codecs. For better compatibility your netmeeting friends
should install the MS-GSM codec.
You should go on the IRC channel for interactive help. Im tehre now for one
hour.
