Hello all!

I have edited my .asoundrc file:

pcm.ch51dup {
type route
slave.pcm surround51
slave.channels 6
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
ttable.0.4 0.5
ttable.1.4 0.5
ttable.0.5 0.5
ttable.1.5 0.5

So I can play stereo files over all 6 speaker, but sound quality is VERY BAD!! The sound is like from old platte.
Where is the problem?
