Can't get my audio to output through HDMI (ATI)

I tried to look for previous threads on the topic but ended up with alot of threads about the old m15 and others regarding nvidia cards.



I have a 5850 GPU and was running IDT for my sound management but I've now removed it. My video outputs perfectly through HDMI but I get no sound. My audio devices says that my ATI HDMI audio is unplugged and therefore cannot be chosen to output my audio and I've read page after page of other people with the problem but so far no fix has worked for me.

I had the same issue, and it was down to my HDMI cable. At first I brought a Display Port to HDMI cable which was sold as 'working with audio', but clearly didnt. As soon as I used a known working HDMI cable (with the bundled display port to HDMI adapotor) it worked fine... Obviously, this was my issue, may be completly different for you, but may be worth eliminating the cable as the problem. If you have somewhere / someone else who can test it (between your Blu-ray / DVD player and TV for instance?)

I dont have anywhere else to test it as nothing else uses display port

Do you have the display port to HDMI adaptor that came with the laptop? I know not everyone got one with there laptop, but if you did, try that with a standard HMDI cable.



The only other issue that (from the top of my head, at work at the moment) that may cuase it is older ATI drivers. Anything from the 11.x range will be fine with HDMI audio, so check your drivers.
