I'm having some weird problems with my onboard sound on the Gigabyte P55-UD3L motherboard.
I have 4 I/O jacks on the motherboard and another 2 on the case. The ones on the motherboard are a green front output, a blue rear output, a pink one that doubles as a microphone input and a center/sub output. Also, there's a coaxial SPDIF out. The front has a headphone output and a microphone output. The problem occurs when I connect headphones to the front, my rear output sound does not go away. This is extremely annoying. The software that comes with the motherboard has an option that enables muting the rear output when a front headphone is detected, but is futile.
Has anyone else experienced the same problem?
Is there a problem with my front input not detecting the inputs?
Double check to make sure the front panel audio cable is connected to the FP_audio port on the motherboard. The cable usually has a HD and AC'97 connector. If it's currently plugged in, try switching to the other connector.
