I have a similar feature exposed by alsa (the surround sound feature from the hda audio driver). It is done automatically on the hardware (just like what you're doing in software here except there's no CPu overhead) and exposed by alsamixer. In my case I couldn't have this feature back when using pulseaudio even when changing the channels, only the two main speakers would play. Funnily enough I had the opposite experience.

That will happen in the near future with PA 0.9.15. Sure there is no GUI for it today but maybe "tomorrow" ;-) PA will also automatically probe which combinations for playback and capture are working with your sound card and allow on-the-fly reconfiguration.

I think a GUI would help a lot here. That said, I don't think it is possible to automatically configure this with my sound card: it is possible to connect between 2 and 8 speakers, and there doesn't seem to be any way to detect what the user has connected. If it was possible to automatically configure, the Windows drivers wouldn't ask you how many speakers you had. Rob: right. I think a GUI would help a lot here.

Caskey Wed, 25 Feb 2009 14:47:40 +0000 http://blogs.gnome.org/jamesh/?p=412#comment-765 I too use PA and am happy with it but I would like to note that "edit the /etc/pulse/daemon.conf file and set default-sample-channels to 6" is considered special effort and not automatic by 99.99% of people on the earth, all of which would not be able to do it.

Other than that, I'm all for PA with the promise of being able to stream my audio to a pair of bluetooth speakers while simultaneously playing the audio out of a pair of wired speakers. Multi-room sound system here we come! Haven't tested yet tho, so it may be a pipe-dream :) Well, I’ve come across a couple of bugs where sound intermittently disappears when using PA, but setting to ALSA fixed those.
