My new pair of Logitech g430 is picking up all the sound from my headset. Whenever I am on skype or curse voice all of my pc sounds are picked up by my mic.
Uhh, i guess the on board audio. I just plugged in the headset and started using it.
Then are you plugging into the front panel audio jacks or the ones on the back?
Front
That is probably your problem then. A lot of the time, the cables going to the front of the case aren't shielded very well (or at all) and they can get a lot of cross-talk. Try moving it to the back or to the USB sound card that came with the headset. It should fix your problem.
