No Audio Output device is installed

post #1 of 7
Thread Starter 
I never never never had this kind of problem before ever. I reinstalled my nvidia drivers cuz i was updating my gtx 460 super boost bios update from evga website. After upon install it doesn't detect my audio anywhere in windows. Did i accidently delete audio?


I went in device manager to see if i can fix it and i cannot.

I don't wanna resort to reformatting again and i could appreciate the help.

Would a windows repair fix it or do i need to do a sfcan in command prompt?

Advice?

It shows all NVIDIA High Defination Audio all 4 of them.

This is strange this happened right AFTER i reinstalled my drivers. I wondered if i accidently delete something during custom installed. Wished i paid attention. I did everything.. microsoft fix it for me software didn't detect anything.

Also restarted pc and also unplugged the speaker cord and replugged. Nothing.

Windows update nothing..

scan hardware changes nothing..

I'm baffled.

Don't know what to do..

last resort is reformat blah..


I fixed it.. i found a section where it said unknown device.. i scanned for updates and it fixed it for me.. i must have missed it.

Also last question.. is it ok to run my monitor 59hz? Even it supports 60hz?

I just wonder why does the picture look crisper with 59hz and smaller than 60hz?

Is there a difference or does it affect gaming or should i go back to Nvidia control panel and custom resolution back to 60hz like i had done in the past?

Pretty sure the sabertooth uses realtek, just go here and download the software.

This just happened to me, I've got 2 GTX 480s and I just did a fresh install of Win7. I have a realtek based on-board audio so I went to realtek's site and downloaded their driver package and installed it, got my sound back. Exact same problem as you, old audio hardware disappeared from device manager / sound settings. I also uninstalled the nvidia HDAudio driver.

Well i fixed it.. it was showing unknown device in the device manager so i updated it and it's fixed now and showing Realtek sound. So obviously it was that?.. weird but thanks for the website link for future reference.

Plus i don't know what exact file i need to download but however it's fixed anyways.

Oh can someone clarify about the 59/60hz question sorry? lol.

You would just download the software for your os when that list pops up from that link.

Just run it at the native setting for your monitor, should be 60hz.

I think the 59hz option is more for media (like if you were watching tv on it), but I don't know if that still applies.
