OK, first I thought it was a problem with teamspeak, however this happens with gnomemeeting too.
kernel 18.104.22.168 from current.
via 82c33 audio.
realplayer still works on an audio stream, e.g. any interenet radio.
There is a series of echoes with teamspeak which is worse when I cut the speech quality. This is probably what I am getting with gnomemeeting, but it sounds like motorboating.
teamspeak gave no problems with 2.6.7 & I just decided to load gnomemeeting for a test.
Bet 2.6.9 will be out next week.
