HDMI sound on hp 8530w with NVIDIA Quadro FX 770M
 
It seems that getting output via hdmi on this laptop is "mission impossible".
The only reference of an (unsuccessful) attempt is here:

and it's pretty old.
I tried various newer alsa versions and nvidia drivers version with no success.
I'm currently running kernel 2.6.31.5 (with alsa 1.0.20, previously tried 1.0.21) and the 190.42 nvidia driver but still aplay -L doesn't show the hdmi audio output.

Well, I asked on alsa-users without success

I managed to enable the spdif output on the sound card but that's not enough to obtain sound through hdmi:

Is there a way to know how audio through hdmi is supposed to work? (I mean, it has to be somewhat routed from the soundcard or the quadro acts as a sound card)?

Same here. I guess this problem cannot be solved at Alsa-side but has to be done at Nvidia-side. Maybe a future release of the drivers will fix it ("hope mode" = on).

Well, at least a reply from some insider telling it isn't supposed to work (or if it is, how) would be nice :(

I know the thread is a bit dusty, however, here is a thread linking to the HDMI audio documentation.
