I'm surprised doing the reset didn't solve the problem for you. That may indicate that it is not a problem with the settings but could be a hardware problem.

If you plug headphones in do you get sound through them?


I'll just include the reset procedure for any other DSR-1000 users that may need it.


Reset Procedure
---------------

1) Turn OFF the power.

2) Hold down the [4] and the [0] buttons on the 'Data Entry' numeric keypad, while turning ON the power to the Keyboard.
