Using onboard audio, the sound kicks in and out of 1 side of my headphones, depending on how I tilt my head, regardless if I switch to a different pair of headphones, is it the soundcard ?
ah yeah the tilting the head trick, I wrecked many good head phones doing this. :lol:
seriously it may be the master volume isn't set right and you might have the pan L/R off center. Check this in the Mixer settings of the sound card.
If you open up the audio master controls check to make sure your pan settings are dead center and that the left or right is not muted out.
If you can't find nothing wrong there then check the connections on the head phones.
If that doesn't do it test the head phones in another device not on the computer. If they work there, it's the port you're plugging into or interference from something around there.
[Process of elimination]
