I am running into a problem with my RX-A3080 not detecting my surround speakers when using YPAO. During pre-check I hear the pink noise coming out of all speakers, including the left and right surround, but when it continues to the measurement phase it removes the surround speakers. The surround speakers are are connected using a wireless Bluetooth transmitter receiver pair, which appears to work very well when I use it to drive my front speakers. Could the Bluetooth connection introduce a delay that is unacceptable for the YPAO pre-check?
