No Audio thru HDMI...HELP!

[sephroth777]

A friend just built a HTPC with the following hardware:

Intel E6750
Gigabyte P35-DS4
2GB Gial PC2-8500
HIS ATI HD2600 PRO PCI-E
LG Blu-Ray GGCH20L
Windows XP MCE

He as just installed all the latest windows updates, ati drivers, etc.
When playing a blu-ray movie the movie plays fine in 1080p thru HDMI direct connection to a Panasonic 1080p TH42PZ77U however audio does not work. He tried the optical out to his receiver and that does not work also however device drivers lists no errors. Does anyone have a solution or have had the same issue?

Thanks!

Looking at the specs from the board it doesn't have an HDMI connector so as I understand it you're using the video card's HDMI output. I don't think that the ATi card will pick up the audio and send it through the HDMI. It is odd however that the optical output does not work. Is the digital output enabled on the sound mixer in Windows?

start > control panel > sound / audio device > audio tab > sound playback changed to ATI Audio or w/e it is

Give that a shot

Also make sure he is using the official DVI to HDMI adapter certified by HIS. I know my Visiontek 2600pro will only enable audio through HDMI if the correct adapter is used.

That's what they tell me anyway, I haven't tried to use HDMI yet.

I had a similar problem and it turned out that I was at fault because I didn't realize that the HDTV has several audio settings. I can't recall now what i did exactly, but playing with these in "setup" mode got the sound rolling out perfectly.

The other thought I had thinking about your trouble was if you had gotten the Blu-Ray & sound to work with, say, a computer monitor. Maybe the Blu-ray isn't working.

Hopefully the former is your problem.
