Hello all, last night i went down to watch a movie on my projector and had an audio issue. While watching monday night football everything was working fine. I then switched to watch a blu ray with my Harmony remote and only had sound coming from my left and right speakers? I then tried to change the audio and must have hit a wrong button, because now i get no audio at all. I have the 990, 7125 with a Pioneer BDP-51 blu ray player. The input was assigned correctly per the display on the front of the 990. The audio was on 7.1 per the display on the 990, but, i was unable to change it to any other audio modes? Any suggestions on what i did?

Thanks in advance!
