[GnomeMeeting-list] Bad echo using gnomemeeting



I am getting bad echoing using gnomemeeting.  I have connected two laptops
running gnomemeeting on the same subnet.  Unless I control the audio
parameters very carefully, the audio starts echoing repeatedly.  Sometimes
the echoing goes on forever, getting louder with each echo.

I am using gnomemeeting with Redhat 9.0 and the ALSA audio driver.  I am
controlling the audio parameters using the standard Redhat linux Volume
Control utility in the Sound and Video menu.  I set volume and mike to about
80%.  Neither of those settings seems critical.  If I set pcm and igain to
about 33%, then the echoing is not noticable and I can still hear the audio.
If either pcm or igain is greater than about 33%, then I get echoing.  If
either is greater than about 50%, then I get infinite echoing.  If either is
less than about 30%, then I can't hear the audio.

I have tried connecting the two laptops directly to each other using a
cross-over ethernet cable, but it doesn't make any difference.  It also
doesn't help to disable the video.

I'm sure that this isn't normal, because I haven't found much discussion
about gnomemeeting echoing on the internet.  Does anyone know what might be
causing my problem?
