h2sammo · 12-19-2009, 10:07 AM

ok according to this post: http://www.nvnews.net/vbulletin/show...=124536&page=2 sound over hdmi is elusive with nvidia-drivers.

i am trying to use the composite cable but i still have no sound. can you help me troubleshoot this?

according to these guys: http://code.google.com/p/atv-bootloa...ki/atvhardware
the sound card for the composite is: Realtek ALC885 7.1+2 Channel High Definition Audio Codec but i dont see it in lspci

my menconfig settings inside hda_intel: http://omploader.org/vMzByZg I dont see a Silicon Image SI 1390 (hdmi component). But i do see the realtek codec suport.

no sound...
help?!

Hi
I really think that I didn't understand your problem, but I'll still give it a shot - just delete this if it doesn't have anything to do with your problem.

Are you trying to use the composite cable with its audio connectors because audio over hdmi for nvidia does not work or because you really want to use composite?

In any case, my audio over HDMI is working perfectly - the audio part of the graphics card is recognized as a normal audio card...

...and I just selected in the kernel config the entry "Build NVIDIA HDMI HD-audio codec support".

Cannot be this simple, or?

you are able to get sound on appletv through HDMI with gentoo installed?

how did you do it?

I still cannot get it done (i get video over hdmi and sound over component now). I have the kernel setting you mentioned enabled for hdmi enabled for nvidia.
