[ubuntu] How do I route surround sound?

view story

http://ubuntuforums.org – Hello, When I play 5.1 channel audio files and Dolby Digital soundtracks on my Ubuntu 11.10 system, the channel routing varies from media player to media player. The order of the channels in my WAV files is Front Left, Front Right, Center, LFE, Rear Left, Rear Right. With the Linux version of VLC Media Player 1.1.12, all 6 channels of WAV files and Dolby Digital soundtracks are routed to the correct speakers. With Amarok 2.4.3, Banshee 2.2.1, and Totem Movie Player 3.01 the 6 channels of the WAV files are incorrectly routed, with no sound coming out of the Rear Right speaker. With D (Hardware)
