When I play a sound file using ogg123, the sound comes out the USB DAC, as expected. When I play a sound file using my application (which uses GStreamer playbin2), the sound comes out the internal DAC. I found directions to run gconftool-2 -t string --set /system/gstreamer/0.10/default/audiosink pulsesink gconftool-2 -t string --set /system/gstreamer/0.10/default/audiosrc pulsesrc Those commands had no effect. I am using Ubuntu Server 10.10 and pulseaudio 0.9.22. -------------- next part -------------- An HTML attachment was scrubbed...
