Package: gstreamer0.10-alsa
Version: 0.10.10-1
Severity: normal
When trying to play 2-channel audio on a 6-channel device with alsasink i get
choppy output.
I created a new pcm device as described in the alsa multi-channel mini-howto.
/etc/asound.conf looks like this:
pcm.ch51dup {
slave.pcm surround51
slave.channels 6
type route
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
ttable.0.4 0.5
ttable.1.4 0.5
ttable.0.5 0.5
ttable.1.5 0.5
}
When i try to play some 2-channel audio using the device ch51dup with e.g.
mplayer, aplay, xmms ...
everything works just fine.
But if i select "alsasink device=ch51dup" in gstreamer-properties as audio
output, it gets choppy.
Running gstreamer-properties with GST_DEBUG=alsa*:5 gstreamer-properties
results in the following output:
