Problems with audio on my MPC1000

My MPC1000 stopped transmitting audio out of nowhere. My speakers work on everything else, I can see on my MPC that my pads still work too so thats not the problem. Basically, everything is fine on the MPC but it will not transmit any audio sound.

What do I do? Is there something I can do to fix this? I just don't understand how an MPC could stop transmitting sound...

is the pad to internal sound on?

wheres that?

mode + pad 9 midi tab on the bottom this should be on
