Recently my headphones are playing both left and right channels over both ear phones. I was wondering what the cause is and possible fixes. They are no longer in warranty.
I tried using both on board Realtek HD as well as a usb sound card (ASUS Xonar U3), and running spdif out to my blu ray player.
CPU: Intel Core2Duo E8500 @ 3.2Ghz
Mobo: Gigabyte EP45-UD3L
GPU: Nvidia 660 Ti
Windows 7 Pro 64bit
Realtek High Definition Audio Driver Version 188.8.131.5262 (From the gigabyte website)
Asus Xonar U3 Audio
If soldering skills are required, I do have the ability and knowledge to do it. I don't really want to send them to the repair center for NA, because they are out of warranty and I feel it would be very expensive.
