it for the N900?) and whether it uses GStreamer or not, so any pointers
would be appreciated.<br><br>In the meanwhile, I can say
telepathy-stream-engine is using pulseaudio's source.voice and
sink.voice devices, so I suggest you to do the same. Moreover, it's
possible the crackling noise is due to VAD/DTX: try and setup a call
without those features.<br>
