Re: Sound problems after using headset!
It's normal that you can't use your regular speakers while you have your headset plugged in. Thats just what happens, the headset becomes your primary output for sound when it's plugged in. I have the same headset, and it works the same way for me when I plug it into my pc. I use it for ps2 online gaming normally.
About the low quality and static sound, I would try updating your audio drivers.
When all else fails...Ham Radio!
I still have the same old HP DV9700T laptop I've had for years...still kickin'
