Hi everybody I have some news : bad news but I was prepared to : as of now the alsa codec driver for STAC9271 is not complete : its ADAT output (vendor specific function) support is not complete. I tested with the ADAT output option Matthew Ranostay had added in a patch ( amixer sset 'IEC958 Playback Source' ADAT ) and also having changed the 0x21 pin default from 014521xx to 015521xx (4 being spdif out and 5 being digital out) : when doing so "alsactl restore" responded : unknown hardware HDAintel STAC ; hardware is initialized using a guess method (which is possibly normal ) In jack I only had 2 alsa outputs (allways using card0 device 1 : "STAC digital"). Maybe the problem is that ADATout Node 0x1F is not detailled enough in the driver ? here is COMPLETE codec datasheet (page185 for 0x1F node ; page 155 for 0x21 digOUT node): http://pdf1.alldatasheet.com/datasheet-pdf/view/199321/IDT/STAC9271.html here a alsa-info.sh of me (before changing to 015521xx pin config): www.alsa-project.org/db/?f=297fa42ac3c439e3ca9336d1fa525a2cadabdae6 Hoping to get help to at least try to make it work : I bought intel DP35DP motherboard ONLY for the advertised "ADAToutput feature".
