I just noticed that switching from DD6.1 to DPL2 by pressing the menu-key (thus entering the non-DD menu) on my dvd remote is accompanied by a short "pop" sound in one of my speakers. It's not the clicking sound when the receiver is going from 7.1 to 5.1 amplification. That doesn't worry me. What I mean is a pop coming out of one of the speakers (usually one of them, not the same speaker each time) It happens when I'm watching a movie in DD, and go back and forth to the dvd-menu (which is not in DD, so the receiver reverts to DPL2) Just to be sure, I double-checked all connections, and it definitely isn't related to that. Setting DPL Cinema or Music doesn't matter (I thought maybe switching the cinema-eq circuit from on to off was causing it) Has anyone else experienced this?
