[alsa-devel] In 3.8 kernel alsa only talks HDMI, hardware also has S/PDIF optical

See https://bugzilla.redhat.com/show_bug.cgi?id=919630 for details.

Comment 4 in that bug is from someone who says it looks like the driver only created the HDMI and not the separate optical S/PDIF output.

On my Asus P8H67-V there really are two physically separate audio outputs. I have the optical port connected to my receiver for when I want to pass through the 5.1 audio tracks in movie files and DVDs and the HDMI connected to the TV for more ordinary audio (error beeps from the computer, etc).

In kernel 3.7.9 I could output to both devices (one at a time - never tried simultaneous).

I've seen a bunch of patches in the archives that seem to be related to this, but if fedora 18 has those patches, they don't seem to be working.
