So my Sades SA-708 got opposite stereo Left is right and Right is left only on my PC but only in the front audio jack. I have speakers plugged into the rear jack and I have a program that I can switch between Speakers and Headphones with F9 and F10. In the rear jack the headset is working like it's supposed to. The front jack wasn't working properly with the default Windows 10 driver so I got VIA HD Audio Deck. Is it possible that the wire that is connected to the motherboard from the front jack is connected incorrectly or turned around or something because I unplugged them couple of times and maybe I plugged them incorrectly?
"Is it possible that the wire that is connected to the motherboard from the front jack is connected incorrectly"
that was my first thought...
take a very close look at the connection to your motherboard.
Yes, some older cases don't have standardized single connector for front panel audio and consist of multiple smaller connectors.
This allows you to possibly by accident to swap left and right channels.
