Re: [alsa-devel] [pulseaudio-discuss] Strange hardware: XFX nForce 780i SLI MCP
Yesterday I got an interesting email related to dcaenc support.
The person has an "XFX nForce 780i SLI" MCP board:
http://www.nvidia.com/object/product_nforce_780i_sli_us.html , http://www.evga.com/support/manuals/files/132-CK-NF78.pdf
As you see on page 18 of the manual, this board has no HDMI output, but
there is an optical SPDIF. Strangely enough, this SPDIF is his "hdmi:CARD=NVidia,DEV=0" device.
Given the recent discussions related to dynamically creating PCM devices
for HDMI, I think you will be interested in this alsa-info output.
Is there anything here that would need special treatment by ALSA or
PulseAudio? Or, is this just a misnumbered/misnamed codec?
Check whether BIOS set the internal spdif as HDMI as pin default
The alsa driver prefer HDMI instead of SPDIF when there are two Digital Outs

According to the manual, there is no such setting in the BIOS.

The driver use the first digital pin's type HDMI or SPDIF , you need to modify the logic in hda_generic.c when type of two digital pins are different
