Is there any documentation about that topic available? I only found some register descriptions, and used them (with some trial and error) to enable s/pdif in and out. It's clearly an experimental feature. It should not be a big problem to enable s/pdif only if compatible parameters are used, with documentation available. But I do have problems with lost or modified data - for testing purposes I connected s/pdif out back to in, and piped a textfile through it (turn your stereo off before you try this ;-) ) Some months ago I did an interesting observation: Corruptions were worse on an idle system! As soon as I started to play music on a second sound card, I saw nearly no lost bytes any more. I'd really like to hear if other people have similar problems. Perhaps I just got a bad sound card? Jan
