Thanks a lot for the patches, the external rate switching on Juli now 
works perfectly (not tested on Quartet yet). One can tell you are 
seasoned in kernel development, I would get lost in the synchronization 
and workqueue facilities.

You are right, that would disable update of other controls informing 
about incoming SPDIF details. These are useful in internal clock mode 
too - if the soundcard is master for the spdif chain. A new control 
would make sense then.

I am leaving for a week, then I will test quartet and the PM features.

Again, thanks a lot for the patches.
