Hello Stephan, > Did you try HCT 10 as well? I've read somewhere that the > relevant test cases were removed in HCT 11. > Can't check it here because I've not yet installed HCT 11. I thought it would be a good idea to run the latest tests. I installed HCT10 and indeed you're right (as expected ;), the AC3 fails the positioning tests on the KS pin and waveOut devices. Strangely enough, DirectSound passes all tests but this is the one that doesn't work correctly using real applications???
