This isn't ready for prime-time just yet -- while adding surround sound
support, I ran across a bug that shows up in this version which can
cause the playback to go away if the formats of the mixed voices differ.
I'm not sure if it is a SW or HW issue, and the playback loss is
sometimes gone until the module gets reloaded.
