Clemens,
You don't want to be reading chip registers all the time.
It's *very* expensive. Cache any values that don't change
in a local struct if they get referenced regularly.

You might find the mmio_test results interesting.
It would be great if you could add one or two audio devices
to mmio_test program here:
	svn co http://svn.gnumonks.org/trunk/mmio_test/

Please send a patch to Harald Welte <laforge@gnumonks.org>.

thanks,
grant
