My Yamaha is doing the opposite. In the "Neo 6 Audio" position, I am hearing voice from my center speaker coming out of my left speaker a few seconds at a time.
Also, I tried to use the Microphone to set up the speakers again and it keeps telling me to plug in the Mic, which it is. Lastly, when I used to turn on the speaker the Volume was the same as it was when I turned it off. Now there is no sound when I turn it on, and I have to turn up the Volume. I was fooling around with the "Volume Trim" on the Receiver. Possibly that may be the problem but I don't know what to do to fix the Volume problem.
