Well I use optical out from my sound card to the receiver. I've always been able to choose whichever speaker I wanted to get a measurement of all the speakers. It isn't receiving any measurements from the SPL meter.

When I calibrate the SPL meter levels to 75db, I can run a few sweeps and the measurement seems to stay at the calibrated level then tells me "the highest leve in the measurement is just -99.4db..."



Edit: its always been on "right" but changing it to left hasn't made a difference.
