Here's the relevant snippet of my asound.conf: # Terratec Aureon USB 5.1 MKII # software mixed, multiple access in output only pcm.dmix51 { type dmix ipc_key 12347 slave { pcm "hw:2,0" channels 6 } } pcm.aureon { type route slave.pcm "dmix51" slave.channels 6 # Front Left ttable.0.0 0.7 # Front Right ttable.1.1 0.7 # Rear Left ttable.2.4 1.0 # Rear Right ttable.3.5 1.0 # Center ttable.4.2 1.0 # LFE ttable.5.3 1.0 } ctl.aureon { type hw card 2 } The (Rear Left, Center) and the (Rear Right, LFE) pairs had to be swapped. Also, I attenuated the Front Left and Front Right channels somewhat.
