Hi again, Please any developper try to make ADAT output feature of sigmatel/IDT STAC927x codecs (used on most intel HDA media and extreme boards) actually work in ALSA. ADAT is a great feature and I am an ALSAonly user so I really need your help. here is the codec datasheet http://www1.idt.com/products/files/17122877/STAC927x-DS-0-7_IDT.pdf Can some of you read the 0x1f ADATout converter (page185-188) and 0x21 digitalOUT pin complex (page155-159) and compare them with the sigmatel alsa driver and sigmatel stac927x patch to see what controls are still missing ? I can test your work and more... I will help as much as I can, thanks in advance, Eric > Hi all, I bought motherboards intel DP35DP and DG33TL and just tried > ADAT output in Alsa (ADAT output on them is proven to work under windows). > I wrote the command (thanks to the work of Matthew for the 'IEC958 > Playback Source' control.28 setting) : > amixer sset 'IEC958 Playback Source' ADAT > > Here is my resulting alsainfo: > www.alsa-project.org/db/?f=cb01bf4f7bc62fe69f36bc1a4bbc0dbcace20605 > > It still does not work > I think the reason is that contrary to the windows driver the > Node 0x21 is still unchanged : > Pin Default 0x01452150: [Jack] SPDIF Out > whereas it should be better with : > 0x01552150 > > How can I change my computer from the Pin default config to this > alternative Pin config ? > Thanks a lot, Eric > >> Hi Steven, >> I have studied the hd audio documents : >> Please make sure the pin default is actually 015521xx when in ADAT mode >> (instead of config default 014521xx ) . >> >> Please copy me your alsainfo script if it still does not work. >> Matthew Ranostay is right : really not much is missing or wrong for ADAT >> to work. >> Thanks everybody for future help, Eric >> Tellman, Steven a écrit : >>> It doesn't work.
