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 ?
Anybody has any other idea to help ?
Thanks a lot, Eric
