Hi there, please can anybody assist me with your expertise, I don't know if I should be posting in the sound forum or the graphics forum as this kind of applies to both.

Basically I've had a setup for years on my current PC that has always worked until recently. My setup is I have a gaming PC that plugs into my AV receiver and my AV receiver plugs into my projector.

For years using windows 7 and using the shortcut Key "Windows-P" to set the display output I have always been able to just select either "EXTEND" or "Computer Only". Anybody who has ever outputted to two displays or had two monitors connecting to one graphics card will know what I mean by this.

Basically the problem has come now that since building my new PC and reinstalling a fresh install of windows 7 onto my SSD. I now find that I have to have the output set to "Duplicate" in order for my AMD graphics card to output the sound to my AV receiver speakers.

If I have the output set to "Computer only" there will be no sound, if I have the output set to "Duplicate" there will be sound but there will be screen tearing on my monitor as its 60hz but before I never had to use duplicate I just always left my computer on "Extend" for years, even if the projector was off I could play games on my PC with one monitor and have sound and no screen tearing and everything was perfect. So this is very annoying.

Basically I need to know if there's some way I can get everything back to how it was before? Can I somehow force my graphics card so output sound when I set my desktop to "Extend" or "Computer only" ?

As of right now if you set the computer to "Computer only" and then go to "Playback devices" in windows the HDMI sound device disappears, only when I choose duplicate will it return.

Thanks in advance for all your help and I hope I've explained this annoying problem ok.

EDIT: I think if I cant resolve this problem because it annoys me so much I might have to buy another sound card that has HDMI slots so I can output the sound that way. I have a separate standalone sound card at the moment that has optical and I plugged that into my AV Receiver but that only outputs 2 channels so that's no good either.

All i do is right click on the speaker then from the pop up menu select playback devices. In there you should see your amd hdmi device. Right click and set it to default playback device and you should have sound.

Hi there, thanks for your quick reply, the HDMI playback device appears in the sound devices menu for me to choose, but only when I have windows set to "Duplicate" or "Extend" if I choose "Computer only" or "projector only" there will be no sound.

The reason this bothers me is because if I have it set to duplicate I have screen tearing in films and games. And if I have it set to extend I have to have the projector on at the same time, otherwise I cant have sound.

It's like a stupid bug that's suddenly appears and I never used to have this problem.

EDIT: Right now I basically have to have my projector on at all times, even when I'm not using it, I have windows set to Extend, and everything works great, but it just means it's a trade off, because I'm wasting my projector bulb life :confused:
 
In the Catalyst Control Centre there is an audio Tab have you tried changing anything in there. It's not something i use much, just now and then to view movies on my TV.
 
Just a thought. When your in Computer only mode try going into the playback devices. Right click and make sure you can view disabled devices. If the AMD device is there try enabling it if you can.

Theres not really any options in AUDIO section for me to change tbh, I just tried installing latest drivers too. I changed setting each display to primary to see if that made a difference but nothing seems to change. I'm starting to wonder if its something to do with the AV Receiver as well, like maybe its a handshaking issue but not sure.

Could maybe rule this out by testing on a small tv with hdmi if you have one.
 
I'm pretty sure my friend had the same issue with his AMD card, he had to flash another BIOS on it, in the end he went back to nvidia & that solved it.
