Can't tell you anything about code itself, I don't know much about
drivers programming. However can more-or-less sum up current
(last-known?) status:

1) AFAIK tested only on one RS690 (do you have some RS690 to test it?
guess would be nice)

2) Works for sending "normal" sound as well as pass through (both AC3
and DTS). Earlier reported problems were caused by kernel modules for
alsa.

3) Doesn't cause regressions on M82 (RV620)

4) I still wasn't able to test second version of patch for regressions
on RV635 :/ I'm fighting with my Seagate 7200.11 "black serie" which
switched itself to some /emergency/ mode.

5) Last time there were sill some audio drop outs on RS690. Christiaan
van Dijk noticed some interesting clocks relations:

If there were some more interesting discussion since (5) I wasn't included ;)

I'm very interested about that part:

I belive I also experienced that. Playing some movie on my notebook
(1600x900) was smooth, but not anymore after switching to 1920x1080 HD
TV. I have to test that, measure somehow. Will post if I notice
something.
