Turntable connection. I have RXV340 with a turntable and mixer attached in CD digital input jacks.

Question

I have RXV340 with a turntable and mixer attached in CD digital input jacks. A DVD player is also attached using 5Ch optical input jacks and works perfect. However, I cannot get sound for when the turntable is playing. I/O Assign is set to 1A DVD and 1B CD. Input mode is set on CD for turntable.
