Hissing in Realtek Headphones and Speakers not Disabling

[lopploio]

Hi, everyone

I just recieved a computer that I purchased yesterday and everything was working fine on it until I went to go plug in headphones. I plugged them in using the front jack and I got this whining hissing sound. I tried using the back jack and the sound went away. Another problem i'm having is regardless of what jack i'm using is that whenever I plug the headphones my speakers don't turn off and sound goes though them instead of the headphones unless I set the headphones as the default device.

Any help would be appreciated.

Make sure your front panel audio is plugged in. Click the start button and typr sound in the search box, click on change sound card settings. Set the speakers as the primary device. If the set up is right the headphones will take over from the speakers. From the way you described it, it sounds as though the front panel audio cable is not plugged in, or is not seated completely.

I've returned the computer to the manufacturer for a replacement but before I returned it I tried removing the usb speakers and the front jack still hissed.
