[GnomeMeeting-list] Horrible 2-second echo on SuSE-based system



Hi,

We have a gnomemeeting setup, the stock out of the box installation that came with SuSE Linux (8 I believe, a uname -a returns

Linux (nodename) 2.4.19-4GB #1 Fri Nov 8 14:37:03 PST 2002 i686 unknown

It was working perfectly for us for some time, but lately someone messed with the sound settings, and now it has a horrible 2-second echo for all remotely connected participants unless we click the audio mute button on the GM control panel (so that the outgoing audio rate is set to zero). Note that we do not hear this echo locally.

We have a hardware echo-cancelling mike hooked between the microphone inputs and speakers, as we always have, and have tried various settings of the internal GM echo cancellation with no luck at suppressing the echo for remote users. That echo goes away as I said if we suppress our own audio transmission.

The odd thing is that it worked fine before, and we have not upgraded or altered the GM setup or operating system specifically to avoid messing up the GM setup, as we use this system essentially for videoconferencing only. I am wondering what options we should have turned on or off, muted, etc. under the all-purpose "Volume Control"panel SuSE provides that can be reached by right-clicking on the menu-bar volume symbol, or other checks we can make from the command line for example to see what can be done to suppress this echo. Help from this list would be appreciated.

Thanks,
Alan
