Reset the remote control?

What is the source of your sound? By default, receiver will use only those channels that are used in the input signal - if you play CD in stereto, it will use only 2 front speakers. If you play DVD with 5.1 audio, it will use all 5 speakers (+ subwoofer if you have one).

However you can use one of the bulitin "sound field program" modes to mix the 2 channel stereo music to all speakers. On front panel, press "PROGRAM < >" buttons to select the one you like. Or on remote control, repeately press MOVIE, MUSIC or STEREO buttons. You can check your manual for description of each sound field program.
