Hi again. Thanks so much for your work on the AD2000B with this board! I followed your directions and finally have sound working. Although I haven't tested recording or any other I/O. I'm using the non-HDAEnabler method with your DSDT.

I also tested your scenario and get the same results; shutdown/restart/sleep all work except when shutting down or restarting after sleep. On my system it looked like all processes exited fine but then it just "hang" at a black screen with the case/cpu/gpu fans still idling.

I'm willing to test any other ideas... This sleep/restart issue is a hassle but frankly right now I'm just happy to have the rest of it working Once again I'm on 10.5 not 10.6 yet.
