I think you should first figure out how to make speaker-test work as expected in the 8-channel mode. This is the command to test: speaker-test -D surround71:0 -c 8 Once that works, it should be possible to make Pulseaudio work too in the 8-channel mode. While testing, it's a good idea to prevent Pulseaudio from accessing the sound card at the same time. Either you can stop pulseaudio ("pulseaudio -k" or "killall pulseaudio"), in which case you should also disable autospawning, or you can run "pasuspender bash", which starts a new shell and will stop pulseaudio from using the sound card as long as the shell is open. Autospawning is disabled by putting "autospawn = no" to ~/.pulse/client.conf. > Just about any hint would be very helpful. :-) I don't really have any advice for how to fix the situation if the speaker test doesn't work. Some other people on this list might have some hints... You could also on the Alsa mailing lists. I don't know which one would be better, alsa-devel or alsa-user... -- Tanu
