I recently upgraded my graphics card from an XFX Radeon HD 6850 1GB to an MSI Radeon HD 7850 2GB. (Windows 8 x64)
The TV is a Vizio E500i-A1
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. 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.
And CCC says that my display doesn't support audio when I know for a fact that it does.
What can I do to fix this?
Also, it might be worth mentioning that the Sound Manager takes a lot longer to open than it used to. After I click on Playback Devices it takes about 30 seconds to open.
Update: I tried reinstalling all my graphics drivers, including the AMD HDMI Audio Drivers. That fixed the issue for a few hours and then it stopped working. 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.
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. (Digital Audio (HDMI) instead of Digital Display Audio) pictured below:
I need to get this fixed, the audio from my TV has to start working, so I'm opening a bounty.
When you upgraded your drivers, did you also select to install/update the "AMD HDMI Audio Drivers"? – Lennart – 2013-04-18T11:03:53.040
They're part of AMD Catalyst, you can't update them seperately – Mark Kramer – 2013-04-18T13:40:05.490
You can select/deselect them when installing Catalyst: http://verrytechnical.com/wp-content/uploads/2011/06/Catalyst_Install_5.png

Actually, I was wrong, nothing fixes the issue. I tried reinstalling my graphics drivers alone with AMD HDMI Audio drivers and that fixed it momentarily, but it stopped working after a few hours just like it did when I first installed the card. And the same thing happens even if I don't install the drivers. I'm lost now. – Mark Kramer – 2013-05-06T02:11:22.937
have you tried it on another TV? Maybe you need to upgrade your tv's firmware – Jason H – 2013-05-09T23:53:41.497
Perhaps it coincides with the machine going to sleep? – LilCodger – 2013-05-10T21:08:51.693
I believe that you are not confirming one of the great answers here in order to let your bounty expire. Do not do this. It is not how this organization works. – HelpingHand – 2013-05-12T21:28:46.403
The quality of the answer matters not, an answer is awarded a bounty when it answers the question or solves the problem in the original post. Neither of the answers did that so neither of them get the bounty. If you think they're so great, why didn't you upvote their answers? – Mark Kramer – 2013-05-13T16:07:13.150
Oh you were one of the answers. Anyway, no your answer didn't do anything for me, those were all some of the first things I tried. I upvoted you for trying, but I can't reward the bounty for it. What happens when a bounty expires without being rewarded? – Mark Kramer – 2013-05-13T16:17:25.953
Ugh, the bounty just disappears if I don't award it, if I knew that I would have just given it to you, now it's just gone. – Mark Kramer – 2013-05-17T08:23:44.263
