Hm, that might work, but note that, once when the stream is set with
the disconnected state, it won't be taken back to the normal state any
longer on most sound backends.  That is, it'll be gone and won't
revive unless you completely unload and reload the whole stuff.  If
that's the intended behavior, that's fine, of course.  So just to make
sure.


thanks,
