No sound from Yamaha Clavinova CLP-150
I have a Clavinova CLP-150. Lately I've been playing around with some MIDI-stuff, connecting my Clavinova to my PC and playing around. It works fine with the computer, and I can easily record stuff etc. When I do this, the sound comes out of the computer-speakers. When I just won't to play piano with just my Clavinova, no computer or midi stuff, it doesn't work. No sound comes out of the speakers when I try to play. I've tried to reset it multiple times, but it still doesn't work.
What to do?
Sorry 'bout my bad English
