ALSA HDMI output not detected

[s***@orange.fr]

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?
