So when my monitor resumes from standby my sound disappears (running over HDMI). I am running windows 8 with 12.11 beta and a 7850. I've tried 12.9 and 12.10...same result. The only fix is to either reinstall drivers or reboot. This did not happen with Win7.

Help plz. :confused:

The only solution I've found is to disable standby mode. Between Windows 8 fast boots and my SSD I don't really miss it to be honest, I've just got into the habit of turning the computer off if I'm not using it and it only takes a few seconds to start it up again. If I'm rendering something then I just turn off the screen and let the PC chug away, which has the same effect as the screen standby but doesn't cause the driver to lose the HDMI audio.
 
this is one of the main reasons i changed over to nvidia :)

couldn't find a fix and every time I turned my pc on before my tv then no sound :(

I had this on windows 7 and 8
 
A workaround that fixes sound for me is...

In CCC go to My Digial flat panels -> LCD override
Enable LCD override and apply, disable and appy and sound should work.
 
me me me me me !!!!!!!!!

Driving me nuts, have to reboot every time, have tried a few fixes but none have worked. Even worse the bloody thing insists on detecting my amp / tv on every boot despite neither being turned on, meaning i have to disable the extended TV in CCC, which means once thats happened i cant extend again and get sound via HDMI back once i actually want to extend to my amp / telly.

As it happens i've now connected my co-ax from my sound card to the amp, so it saves me if i want to watch DTS / Dolby Digital etc but then have to pee about in whichever media player i'm using.

So yes its massively annoying and am close to ****ing off 2 x 7970s and going to Nvidia to see if the grass is truly greener on the other side, despite being with ATI since the 4870s.

Oh and PS the LCD overdrive fix that works for some ( inc MetalMackey above ,damm you ! ) , doesnt work for me ... grrrr.....

PPS thinking perhaps numerous AMD driver installs over time had buggered something up , i did a Windows 7 re-install 2 or 3 weeks ago and went straight to 12.11 betas, no difference, still broke ...

I've been back and forth over the years. Never had a lot of problems with either side, but this is truly annoying.

Have you tried the latest 12.11 beta 11? I know there was some audio issue fixed somewhere in the 12.11 betas but not sure exactly what or when.

EDIT:

Looks I am mistaken. Audio issue had to do with Ubuntu:

FEATURE HIGHLIGHTS OF THE AMD CATALYST 12.11 BETA11 DRIVER
AMD Catalyst 12.11 Beta11 is now available, and includes the following updates:
(Please note that AMD Catalyst 12.11 Beta11 includes all of the fixes found in previous versions of AMD Catalyst 12.11 Beta)
  • Improves performance in Far Cry 3 (up to 25% with 8xMSAA, SSAO enabled @ 1600p, and up to 15% with 8xMSAA, HDAO enabled @1600p) (AMD Catalyst 12.11 CAP2 must also be installed)
  • Resolves a sporadic system hang encountered with a single AMD Radeon HD 7000 Series GPU seen on X58 and X79 chipsets.
  • Resolves an intermittent hang encountered with AMD Radeon HD 7000 Series GPUs in a CrossFire Eyefinity setup.
  • Resolves image corruption found in certain DirectX 9.0c titles
  • Resolve missing fonts issue in XBMC
  • Resolves no video issue found in Media Player Classic Home Cinema when using full or half floating point processing
  • Resolves stability issues found in the previous AMD Catalyst 12.11 Beta8 driver for Linux
  • For users experiencing issues with HDMI Audio under Ubuntu 12.04, users should try installing the “dkms-hda - 0.201211291615~precise1” package from https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+packages and reboot; this will resolve the HDMI Audio issue found in Ubuntu 12.04
  • AMD Catalyst 12.11 CAP2 has just been released, and should be used in conjunction with AMD Catalyst 12.11 Beta11
    • Improves Far Cry 3 performance for single GPU configurations with AA enabled

I'm using 12.11 beta 11. fail. If it doesn't get fixed in the next few weeks I will buy a NVIDIA card this round even though the 7850 performs amazingly for the price and I don't particularly like NVIDIAs offerings in the 6 series.
 
Right, speakers in the monitor then? The reason I ask is because I don't have this problem, but I'm going to the display via an AV amp.
 
Well that is essentially the same thing, I'm guessing the monitor is the audio device. Does it vanish after returning from sleep?

I don't know why AMD have been messing about with the HDMI audio stuff, they broke it at idle clock months and still hasn't fixed. I run 500mhz idle clocks and it's fine, but it's still not right.

I no longer have amd on my main pc but can explain to you what happens.

Any time you turn on the pc before the tv/monitor or the pc goes to sleep then the hdmi is no longer recognised as a sound device.

Under playback devices it will say "not plugged in"
 
It's not restoring the handshake then. If you unplugged the HDMI and reconnected it may come back. Even if it did, it's still not right. It shouldn't matter in what order you turn on HDMI devices it should do the handshake and connect. I mean my SkyHD box doesn't care! :p
 
Hmmm, mine doesn't care which order they are switched on, it still works fine. I do however have the standby problem, when it wakes up it no longer recognises my TV as an audio device.
