Hi,
I've been working on this small media PC and have been trying to enable
7.1 (8) Channels from my Audigy 2 card and haven't got very far.
Setting the number of channels=6 or 8 in /etc/pulse/default.pa results
in messages like the following:
pulseaudio[6008]: alsa-util.c: device doesn't support 6 channels,
changed to 2.
Is this because my card drivers don't support 7.1? or is pulse somehow
going via alsa and that's causing a mess?
I've attached the output of pactl
Thanks
