Results are soso: -ALSA does not complain anymore about slave.channels 6 -speaker-test does not complain anymore about -c6 -my receiver sees the stream as multi channel pcm, not stereo anymore -but whatever I try with the ttable config, I can only get sound through the left and right speakers. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
