[alsa-devel] ALSA HDMI output not detected

Hi guys,

I opened a bug about HDMI sound output not detected on an NVIDIA optimus laptop. I don't know if HDMI sound card detection is up to ALSA, the kernel or the video driver. Could anyone give me a clue so the bug can be routed to its correct destination? Link to the bug: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1377653
