4870 X2 HDMI out with digital sound?

[davejuk]

I have an ATI Radeon 4870 X2. I connect it to my HD TV via a DVI-HDMI cable.

This requires me to have a seperate analogue audio connection. Is there any way to connect it to my TV via the HDMI with combined digital audio?

In audio devices in control panel select HDMI audio as active device, should work IIRC from when I had a 4870.

Oh and DVI -> HMDI cable or HDMI dongle and HDMI cable? the audio may not work if it's the former.

Yes, I have "High Definition Audio Device" in my device manager (Vista x64).

Although I'm aware there are 3 different flavours of DVI, my understanding was that it was video only. My 4870 X2 only has 2xDVI and an S-Video out.

I can't understand for the life of me how I get the sound out of this thing.

The 4xxx series cards all support audio through DVI via the DVI>HDMI dongle. USe that and an HDMI cable and you'll be laughing.

I'm using the little grey DVI-HDMI adapter that came with the card. I connect a male-male HDMI cable to that. I get nothing from my TV...

Nevermind, I got it. The TV audio detect audio didn't pick it up immediately.

Thanks for your help guys.

Glad you got it working, not least because I plan on doing something similar myself soon
