HDMI from Graphics Card to TV
Hey. I'm stuck with not being able to get sound from my PC. I've got the HDMI coming from my Graphics Card going to the HDMI on my TV and I get nothing. I've had a look at the various different playback devices in my Sounds menu, all appear to be 'Working', I've set each as default but I still get nothing. Anyone got any ideas? I've tried searching the net and can't find anything.
http://www.tomshardware.com/reviews/radeon-hd-5770,2446-3.htmlQuote:One of the features I was most excited about at ATI’s press briefing aboard the USS Hornet was the addition of a protected audio path, which would allow cards based on the Cypress (and now Juniper) GPUs to pass encoded Dolby TrueHD and DTS-HD Master Audio streams to a stereo receiver.
Actually, this is more about allowing the playback software to pass that audio data. The path has to be implemented in such a way that the high-definition soundtrack doesn’t become accessible to a malicious user who’d happily intercept the DRM-free audio. ATI and CyberLink worked closely together to enable this functionality right as the Radeon HD 5870 was launching in a beta build of PowerDVD 9.
Is this relevant?
Just check a few details of the graphics card. Video cards do not have audio built into them, usually. However, HDMI output connectors certainly are supposed to have audio signals in them. And in the case of ATI cards (but not some others), they added audio signals to unused pins on DVI output connectors (DVI does not normally have audio) just so that you could buy the RIGHT KIND of adapter to "convert" DVI out to HDMI out (including audio). So IF you have such an adapter, is it the right kind, and is your video card one from ATI that has this feature? However, if your output port is a true HDMI in the first place, the adapter question in not relevant.
But one step that may be required in either case is, how do you get audio into the video card? In some cases there is a small cord you must connect from a mobo (or audio card) connector to an input on the video card to get it there. Does your video card need that?
