I'm not sure if the Intel/0x2806 codec is the HDMI codec.
Anyway, AFAICT HDMI codecs are hardcoded to be disabled. I suppose the
necessary code to make it work is missing.
>From the azalia_init_codecs function in src/sys/dev/pci/azalia.c:
/* Use the first codec capable of analog I/O. If there are none,
* use the first codec capable of digital I/O. Skip HDMI codecs.
*/
Also on the TODO list in src/sys/dev/pci/azalia.c:
* TO DO:
* - multiple codecs (needed?)
* - multiple streams (needed?)
I have an ATI graphics board with a separate azalia controller:
azalia0 at pci1 dev 0 function 1 "ATI Radeon HD 5470 Audio" rev 0x00: msi
azalia0: no supported codecs
In my case I think the only need is the addition of HDMI audio support to
azalia. In your case, assuming the Intel/0x2806 codec is your HDMI codec, I
think multiple codec support is needed as well.
For now I think you're out of luck with HDMI audio.
