Double-check to make sure dmix6 specifies 'channels 6', and not 'channels 5' 
or something. Other than that, I don't know. What alsa-plugins version do you 
have?

For surround51, perhaps you could try setting 'period_size = 884' in 
alsoft.conf. That will give a nice round 20000us, as opposed to the 
23219.955us that 1024 gives.
