If you wired them up, just unplug those. And check the motherboard for default setup if there are jumpers when you use the front jacks.
This area can be daunting as to sometimes a motherboard has an odd way of installing audio drivers. I will not be covering that. Head to your motherboard maker's forum about that to save time.
What do I do? I install an audio card since labor is more than the under 10 buck card.
I built a custom pc a bit of a while ago. The only thing I couldn't fix was the audio issue. Both the front and back ports don't work and I have no idea why.
My pc recognizes it when a device is plugged in, the drivers say everything is fine and the headphones work too. But all I hear is static, it's responsive because depending on what audio I play, the static either gets worse or quieter.
I put this off at the time because I could just run it through hdmi and plug in my speakers to the monitor and everything sounded fine. I also have a headset that plugs in through usb and I've had no issues with that either.
I finally have the time to tackle the issue again, but to all my efforts, nothing. I've tried installing different drivers, updating my system, double checked to make sure everything was plugged in properly. Nothing. Does anyone know how to help?
