ran across an audio error on an AXC-603G-UW13that I bought from Walmart over a year ago

I've always thought that the audio on Youtube sounded strained on this box. I accidentally found out why: I am working on a project that signals the occurrence of something by making a sound in one ear or the other. It won't work on this AXC-603G Windows 10 box because THE AUDIO OUTPUT JACKS AREN'T CONFIGURED FOR TRUE STEREO!!! If you plug an RCA splitter/adapter cord into the line in jack, you should be able to touch each RCA center pin and hear a hum sound come out of the corresponding earphone. Instead, on this box, if you touch either the left pin or the right pin, the sound comes out of both earphones in mono with a very slight emphasis toward the channel that SHOULD be the only one making a sound! It doesn't matter whether the headphones are plugged into the "audio out" jack on the back or the "headphone" jack on the front, the sound is basically monaural. I've even gone into the Realtek driver interface and set the balance control all the way to one side; the effect is that the other side disappears totally and the chosen side comes out in monaural on both headphones, This is a total misconfiguration of an audio channel!!! I even took the side off of the box and did a continuity test from the headphone jack to the HD Audio connector to see if anything had accidentally gotten shorted. The left, right, and ground circuits all showed up exactly where the HD Audio pinout shows that they should and ONLY where they should. This motherboard must be blending the channels just before it sends them to the outputs. Any suggestions would be appreciated.

you can try a live linux distro as Lubuntu, so you can test the audio without installing any new OS and check if it's an hardware issue.
