I have a yamaha MG124cx . It ran fine until I moved. Now the individual volumes on the in side dont seem to work and I cant get sound out of the stereo jacks. The monitor and head phones work fine. My speakers are unpowered. Again they work with monitor plug. I tried EVERYTHING. Ive hit every button on the thing. I am using unbalanced jacks not the balanced plugs (1/4 plugs)
