seanthomas Posted April 29, 2009 Share Posted April 29, 2009 Background: Gigabyte G31M-S2L ALC662 (has SPDIF header - 3 pins) NVIDIA 9600GT (HDMI + DVI - has header for SPDIF to pass-through to HDMI) I connected the patch cable that came with the graphics card to attach the SPDIF header on the motherboard to the SPDIF plug on the 9600GT. I have tried various kexts available for ALC662 and audio output through line-out works great on all of them. Currently I am running the "Legacy HDA" version (seems to be the cleanest). There is a "Digital-Out" option, but I am getting no output via the graphics card. I am using an EFI string for the graphics. In Vista, I am able to output audio through the graphics card, through HDMI to my TV but no such luck under OS X. So I know that everything is physically hooked up properly at least... My goal is to have an HTPC that has basically two connections on the back (Power + HDMI ... no clutter). Almost there... Anyone have ideas/advice? Thanks in advance.

gary52 Posted April 30, 2009 Share Posted April 30, 2009 Hi, I have a similar issue. My MB is a G31m-ES2l which has an ALC883, had hoped that with my 9400GT card I could get both video and audio down the HDMI port. Unfortunately every kext I've tried doesn't work with this and I am not knowledgeable enough to modify things myself. just have to wait until someone smart enough and needy wnough does it! best of luck Gary Link to comment https://www.insanelymac.com/forum/topic/164296-spdif-audio-pass-through-g31m-s2l-9600gt-hdmi/#findComment-1145200 Share on other sites More sharing options...
