thomas added this to the linux driver, too, although i don't know if it's already included in the recent alsa version ... he sent me a patched source file some times ago ... anyway, it didn't help on my machine... i haven't had a look at this screenshot, yet, but can you tell me which registers have been altered in windows? you can use scanpci to get the actual register settings from your devices ... i'd be pretty curious if your windows register settings differ from your linux register settings ... i'll have a look at your screenshots tomorrow ... i'd appreciate if you could send me an output of scanpci of your linux settings that i can compare it with mine ... and if some people with hdsps that are actually working on their machines would provide us with their register settings, we might be able to figure out, where the problem could come from ... cheers...
