I feel there are too many additional callbacks in your patch.
Since we don't need too subtle tuning, can we simplify this?

Regarding the separate rate setting for each stream, we should
consider about Maya44 support, too.

vmaster can be used for this now.  It was moved to core directory
after 1.0.16 release.
