Nvida 347.25 Removes HDMI Audio Device

[Gamer686]

OS: Win 7 x64 Pro Mobo: Asus P8P67 Deluxe (LGA1155) GPU: GeForce GTX 560 Ti (rolled back to 347.09 at present) I have never had any issues with respect to HDMI audio on my TV before with my present hardware configuration. After performing the express installation for the 347.25 update, my TV no longer appears as an audio device. It is not "unplugged" or "disabled," it is simply no longer appears as an option but is still recognized for video. I have attempted the ancient tactics of rebooting, unplugging and plugging the TV back in, rolling back my drivers and doing a clean installation to no avail. Please can anyone help me?!

Hi welcome to the forum

i would suggest trying a restore point before the issue started.

I did not have this issue but I am using a GTX 750Ti . I also use that DDU program so I can install a fresh Video Driver.

Unfortunately I have system restore turned off so that is not an option.

one thing you could check is default play back device is set to the correct thing.

Well; if i were you i would re-enable it; as it does help solve driver issues, etc. at times by enabling you to go back to a point before issues started. So I would re-enable it.

I cannot select it as a default device as it is completely removed from the playback devices menu. Also to update, I have removed the HD audio driver from 347.09, cleaned the registry, and performed another clean install (rebooting along the way), which has not helped at all.

Update: I attempted disabling my motherboard audio (through BIOS) and reinstalling the Nvidia drivers but this did not force an HDMI audio device to appear. The HDTV that is connected via HDMI to my GeForce 560 Ti does display video however, and does show up under the Nvidia control panel as an audio device. Also per Nvidia's suggestion I made my HDTV my primary monitor (and even removed my DVI monitor) but with similar results.

At this point I would try the card in another computer and test if get sound.

The best I can do is try it in my other PCI slot and see what happens. Will post results.

Changing PCIe slots did nothing, and trying to see if the option exists under a newly created profile on my system yielded no results either. As I expected, Nvidia tech support says to just reformat my machine and hope for the best. The windows audio service is starting and running as expected... all Nvidia high definition audio devices under sound, video and game controllers are working properly. Scouring the internet leads me to believe this is a rare problem as I have found similar threads of unresolved issues dating pretty far back but no actual solutions.

Unfortunately I do not own a second PC that can accept this graphics card but if it will really tell me anything about the situation I can find a friend. Thanks to everyone taking the time to read and respond in this thread.

I would try to find a friend to test card in his system then if same problem in his then I would have to think card is faulty.

 

[Gamer686]

I'll give it a shot but I find it hard to believe that the HDMI chip could have possibly died and I would still be getting video. Given the nature of electronics I suppose there wouldn't be any graceful degradation before failure.

From what has been posted, I would suspect the Video Card. The Audio for HDMI is generated in the Video card and separate from the PC's regular audio.

The Intel i5 CPU has Video and HDMI audio. For testing, you could remove the NVIDIA card and enable/use the Intel Video, HDMI for testing to see how that works. If it does, it will also point to most likely problem with the NVIDIA card.
