Windows 7 can't find the speakers/headphones being plugged in

okay the nvidia audio goes through the hdmi connector.
If you right click the speaker icon and disable it as a playback device you should find your normal speakers and headset working properly again.
They operate off the onboard audio device.
I have the same set up here, I use the nvidia most the time because it plugs right into my tv and thus my stereo, but I have to turn it off to make my headset work.

If I know asus it's likely the audio driver they are using is horribly outdated, have you given a look to optional updates in windows update (while nvidia is disabled , as long as it's on, the computer will see it as your active audio device)

...and yup it's from 2009 realtek has drivers from this year up.
You just have to figure out which set covers your audio device.
Realtek

All i got from the realtek drivers was the speaker icon on the bottom right to show that its trying to output to digital audio and it says speakers and headphones arnt plugged in when they are, im still trying the windows update though

I installed all of the updates i could and still NOTHING changed, it still thinks im using digital audio

Just checked again and this time it saw more updates i guess, maybe the last time my internet had a heart attack for a second but o well im trying the update again

Outside of the socket being physically damaged, I'm not coming up with much more.

Must be windows, better get a mac.
