X Rocker Gaming chair only outputs audio thru subwoofer.

I have a X Rocker gaming chair without the bluetooth. Chair has always worked fine, I stopped using it for a few months and now the audio only outputs through the subwoofer and really distorted. I have removed the circuit board and I can't see any ruptured caps or burn marks on it. I'm not experienced with circuit board but I do know circuits and most of the components on here. If anyone can help diagnose it, it would be greatly appreciated. I can't find any pictures online of my exact chair but mine has 3 speakers. I have tried different outlets, audio cables and devices to output audio.
