I unplugged the receiver in order to setup a new tv stand. I plugged everything back in and now there is no sound. There is a message on the receiver saying NG:L R

I have connected my universal SACD/DVD-A via the optical input labeled CD. Dolby encoded music played just fine but DVD-A content and SACD (DSD) would not play. What must I do to hear the hi-rez information on my discs?
