OK, that's fine.  A patch would be appreciated as always ;)

That's exactly what I wanted to implement after 1.0.9, too.

The basic infrastructure for unsolicited events is already implemented
as a callback to driver, but it's never tested yet.

users reconfigure the mixer interface (like .INI file of windows).
This will require a relatively big rewrite...
