Windows 7 Ultimate 64bit
AMD Radeon HD 5450
HDMI going from my AMD card to my Vizio TV
What I did to finally fix this:
1. First I followed this link - How To Disable Automatic Driver Installation In Windows 7 / Vista
2. Opened device manager, went to sounds, uninstalled all drivers for each sound option I had.
3. Downloaded CCC 12.3 - AMD Catalyst 12.3 pre WHQL driver download from Guru3D.com
I didnt check with 12.4 but I bet it would work.
4. Opened it and did an uninstall of AMD software.
5. After reboot; went back to this link: How To Disable Automatic Driver Installation In Windows 7 / Vista
and did the opposite. at this point windows didn't try to install any drivers. You can check this by going to device manager and looking for the warning symbols.
6. Installed CCC 12.3
This fixed my problem of losing sound when I would turn the tv on and off.
7. I then went back into device manager and installed the drivers for my other sound features that were not part of AMD.
I tried to follow the directions above, but to my surprise Windows still auto installed the audio drivers.
I had installed CCC 12.8 and found out that I can't get the sound to come out from my TV (Samsung connected with a HDMI cable). I decided to uninstall CCC and follow the directions above... it didn't work! So after removing CCC 12.8 and installing 12.3, I manually updated the driver and remapped the driver location to the CCC 12.3 folder.
1. Unpack the 12.3 file;
2. In Device Manager, under [Sound, video and game controllers], select the device you want to change (in my case [AMD High Definition Audio Device]);
3. Right click on the device and click [Update Driver Software...];
4. On the new window click on [Browse my computer for driver software];
5. Click on [Browse], by the drop-down box and find the path for the unpacked 12.3 file. Click next and the new/old driver should install.
After I confirmed that my sound was coming out of the TV and that my device was showing ready, under the [Playback devices] window (before the fix my device was showing "Not plugged in"), I installed CCC 12.9 BETA. So far everything has been working how it was designed to.
I hope this helps.
