I have a new HTPC build (it's running Windows 7 Ultimate x64) and it has a ATI Radeon 6450 as graphics card.

When I boot the PC, everything works fine. However, when the TV is turned off and then back on I notice there's no sound anymore. There are lots of other people who have this issue aswell. I've found this workaround however it doesn't seem to work for me.

I have the newest drivers (12.4). Someone said it was fixed in 9.1 but I still have the issue.

  • Maybe the default audio device is switched to an on-board audio, if you have it. Try disabling all other audio devices in device manager. – haimg Jun 10 '12 at 18:28
  • @haimg Unfortunately, it's not working. As seen in the screenshot (language is Dutch): dl.dropbox.com/u/84195929/hdmioutput.png (niet aangesloten means not connected). – Devator Jun 10 '12 at 18:47

You should see this thread. It solves the issue for some user.

In short: The 12.4 drivers are buggy, revert to 12.3 until fixed drivers are released.

  • Thanks, seems it's an issue with 12.4. See this thread for even more information. It also seems to be fixed in the 12.6 beta drivers. – Devator Jun 13 '12 at 9:00
  • This also works on Ubuntu 12.04. Reverting the drivers from 12.4 to 12.3 solved the problem. – speakr Jun 15 '12 at 10:13
