So, what I think it is: Upgrading the video card drivers. But then I upgraded to the beta version of the drivers for my video card and installed using the method I outlined in my answer on that question, and I took my HDMI cabled out of the TV and plugged it back in and that seems to have worked. When I finally fixed that issue, the problem in this question wasn't fixed. Whilst trying to fix this problem I encountered another problem with my video card, outlined in this question. When the problem occurs try to disable/reenable AMD HDMI Audio Drivers: No difference.Update Chipset and BIOS driver: No updates available.

Tried with and without AMD HDMI Audio Drivers: No difference.

Reinstalling my audio drivers (Realtek HD Audio): No difference.I'm going to list the various troubleshooting steps I took and what the result was: I need to get this fixed, the audio from my TV has to start working, so I'm opening a bounty. (Digital Audio (HDMI) instead of Digital Display Audio) pictured below: The differences are that when the AMD HDMI Audio Driver isn't installed my Sound Manager doesn't take a long time to open anymore and names of the devices are different. Today I tried doing it without installing the AMD HDMI audio drivers and the same thing happened it worked for an hour and then the TV starts showing that it doesn't support audio.

That fixed the issue for a few hours and then it stopped working. Update: I tried reinstalling all my graphics drivers, including the AMD HDMI Audio Drivers. After I click on Playback Devices it takes about 30 seconds to open. 6 different HDMI audio outputs (there used to be only one) show up in the sound manager, but all of them show up as being disconnected.Īnd CCC says that my display doesn't support audio when I know for a fact that it does.Īlso, it might be worth mentioning that the Sound Manager takes a lot longer to open than it used to. My HDMI audio output used to work fine with my TV, but when I upgraded my graphics card I can't get HDMI audio to work. I recently upgraded my graphics card from an XFX Radeon HD 6850 1GB to an MSI Radeon HD 7850 2GB.
