Try going under initial settings with disc play stopped. Go under options to SACD playback and make sure it is set to Multi-ch area. Also check your other settings to make sure they weren't changed. I have the same player and sometimes it changes settings on its own. I also noted that when playing 2 channel SACD's I have to set my center channel to large or the sound has no bass. I have all speakers set to large and sub on although my center is actually small. However the DVD Audio works well with center set to small. Go figure. Hope this fixes it for you.
