Hi! I found the manual for your motherboard at http://www.iusermanual.com/motherboard/asus-m4a78-am-motherboard-manual.htm See: http://bbs.archlinux.org/viewtopic.php?id=78058 http://xbmc.org/forum/showthread.php?t=64112 (no solution though) http://fedoraforum.org/forum/showthread.php?t=237371 (no solution) Are you sure you are sending multichannel data to the soundcard? Run aplay -L and for each surround41, run: speaker-test -Dplug:surround40 -c4 -l1 -twav And see what happens. Sorry I cant be more of help. /nisse On Sat, Jan 16, 2010 at 2:30 AM, Viliam Kubis <viliam.kubis@xxxxxxxxx> wrote: > Hello, > > I have a PC with an ASUS M4A78-AM motherboard with integrated VT1708S > 6-channel sound chip in it.
