HI Guys,

I have Asus GTX 780 DC2OC, Maximus hero VI and i 4770K. I installed windows 7 32 bit initially(by mistake) and installed the drivers from OEM discs. I was able to hear everything perfectly on my philips 1080p 47" TV.

After installing Windows 8.1 I was able to hear the audio when I installed the drivers from the OEM discs, but after I updates the drivers using online drivers I am unable to hear audio through TV. The device is shown in the sounds playback devices and it shows metering too.

I installed the bios drivers from Asus using AsusEZ update and also the latest Nvidia GPU drivers from their site. (331.82-desktop-win8-win7-winvista-64bit-english-whql)


I did hear a crackling sound when I tried to play Bioshock infinite.

I though the nvidia HD drivers might Since then I've doing a clean install of drivers with nothing but graphics card and physX drivers check marked. That didn't resolve the problem.

After that I did a clean install of nvidia drivers again with everything check marked for install. That didn't solve the problem,

After that I tried to manually uninstall the drivers(Nvidia HD drivers) from device manager and then windows took some default drivers (I forgot the name but they were some Microsoft drivers) but that didn't solve the problem either.

The audio device is shown in the Nvidia control panel, and windows sound panel. The Realtek device works fine if i try it using headphones.

Any help is greatly appreciated? Any one else has faced this issue?

What doest the crackling sound mean? Is it possible that my card is faulty?

Please help guys! Thanks in advance!

Well i thought of that same issue with my ASUS GTX 560. A video card is a video card and that's it. So your video card only sends video out not audio so i would suggest if your tv has it a 3.5mm to 3.5mm headphone jack from your speaker port on your motherboard the the headphone jack on your tv.


EDIT: didn't read whole post i see that you had audio through your card before updates but not after ill let someone else tackle this one.

Have you gone to your sound card software and selected hdmi as your audio output source?


Yeah, I can even see the metering bars move when I play some audio, and the name of my TV.

I've also gone to nvidia control panel and tried testing there, and in windows sound settings, there is no sound in the tv. It was there on windows 7 and it was there on windows 8.1 initially, but after I updated the driver there was some crackling sound I heard and poof, it was gone. Hate it..

I don't know how or why, but when I went home yesterday, it started working again. I am sure I restarted and checked all solutions before too, it was a pleasant surprise : )

I had this same problem and managed to solve it by experimenting with some things.

After a few hours scouring the web, the only solutions I found were to update my drivers, which was garbage.

This may be unique to me and my setup, but I selected my HDTV from the "Playback" menu with the "Sounds" control panel. From there, I went to the "Advanced" tab, and changed the "Default Format" from a setting that used 48000 Hz to a setting that used 44100 Hz (bit rate did not matter).

I am currently running Lenovo Y510p > HDMI to Sony Bravia HDTV --> Optical to Logitech Z-5500.

My guess is that the Logitech receiver system somehow did not play nice with the 48000 Hz frequency (I am not tech-savvy enough to give a real reason why).
