Yes I am sure dp35dp and some other current intel media series motherboard do have ADAT output possibility thanks to their sigmatel/IDT codec with can do SPDIF or ADAT at choice : www.simplifidigital.com/shopsimplifi/amplifiers-adat-input-amplifiers-c-2_7.html The codec datasheet has a lot of data for the driver developpers : SPDIF to ADAT mode output is explained. But being an idiot-user I can not see if it is implemented in alsa just by reading the driver. (that is I would like an answer from a developper or someone looking at the codec datasheet and alsa driver). I should not have mentioned HTPC as it introduced some confusion. You are right I am not doing HTPC : I do high end 4way stereo : 8 channel pcm at 24bit/44k100hz (from the PC doing active crossover with brutefir) to a 4 way stereo DAC with optorec chip ; optically isolated from the pc. So ADAT and these intel motherboard are perfect for me as long as : -44100 is cleanly supported in HDaudio (no 48000hz resampling like creative soundcards), which I do not know. -The sigmatel codec alsa driver support all the STAC927x functions including at least the SPDIF to ADAT output switch and maybe more... PS: An rme9652 does perfectly ADAT in alsa but they are too expensive and have many functions I would not use (inputs for recording, clock slaving, midi...). I only need clean playback.
