I have an hp DV9347cl with a GeForce Go 7600. HDMI audio out doesnt work with either nvidia or nouveau driver in linux, and only works with an old version of the nvidia driver as described here: http://h30434.www3.hp.com/t5/Notebook-PC-Sound-and-Audio-e-g-Windows-8/No-Audio-from-dv9000-HDMI-to-Sony-HD-TV/td-p/30293 So, is anyone familiar with pass thru type hdmi audio in the nouveau driver? I would really like to get this working since this laptop is used as my entertainment machine for my living room, and I despise having to use windows for this, but right now I have no choice. I have good programming skills and some linux module programming experience, so I can work with someone providing debug info, etc more knowledgeable about this driver if anyone can help. -D
