1st of all it may be a wrong section to post this question so i am sorry.

My question is that if i plug a usb headset then will the rear speaker automatically get muted or i have to do it manually??? and what the best usb headphone in the market if any within 1000 taka... and are usb ones good enough for gaming or voice chat...

Actually my front panel casing audio is a non HD one so if I plug in normal headphones in the front the rear speakers doesnt get muted so i thought usb may be a solution..

help pls...
