|What is the make and model of your computer and whatever headset you are using?|
So Netflix and Youtube audio work fine through your headset?
Is the headset hooked up to a sound card?
Do game's sound work when the headset isn't plugged in?
Does the headset work with games when you use onboard sound?
I am really just trying to figure out if the problem is the headset or sound card. You talked about your headset in the post, but put it under the sound card section.
