Hi! I hope you still get this, although your original post is quite old. I wrote a howto about softvol recently. In the end, I attached my .asoundrc file, which splits my 4 channels in 2 streams (front and rear). That way, I can adjust volume for every channel seperately, because these 2 controls are stereo controls. Have a look at it, maybe you can do it similarly for 6 channels.
