[alsa-devel] intel DP35DP adat supported (STAC927x codec) ?

[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
