Hi all... I moved my system from Ubuntu recently and am having one small issue that I haven't been able to solve; everything else is working great and I'm about ready to move all of my other systems to Arch also, once I've solved this. :-)
The one nagging issue I'm having is with sound. This is a fiber digital connection that was working on the ubuntu install and a couple other distros I play with, but I haven't been able to find the issue in Arch. Sound comes out of only the front-left and front-right speakers. When I do the sound test, it lists all of the other 7.1 speakers, but no sound out of anything other than the front 2 speakers. I noticed that I don't have an asound.conf, so I was wondering if that might help or if it's not needed with Arch?
sound.conf contains the following:
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel/proc/asound/cards contains:
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf9cf4000 irq 22arecord -L shows:

I've never had to deal with true surround sound on a system, but I imagine part of the problem is that the applications you're using don't specify sound channels for the other speakers. In Ubuntu, it probably split output between the other 5 outputs for you. Try http://bbs.archlinux.org/viewtopic.php?id=79820 or http://www.halfgaar.net/surround-sound-in-linux .

Thanks! :LOL: - those were 2 of the url's I've been looking through (in addition to the alsa faq, some stuff on the ubuntu, gentoo and xbmc forums).
I've setup an asound.conf and am about to give that a test.
--edit--
Well, that didn't solve it. I'll have to keep trying. :-(
If anyone has managed to get surround sound working out of more than just the front 2 speakers, I'd love to hear how you did it. ;-)
Mine is connected via digital, so it's beginning to look like I need to set spdif up somehow.
But... Now that I think about it, it 'should' be pretty easy since all I basically need is for it to force all raw audio out the fiber digital connection since the receiver actually handles all of the decoding (dang....it worked great in Ubuntu, now if I can just figure it out in Arch). LOL
Thanks!!
