U-Rip 22 - Sound to computer

Hi to all.
Having a spot of trouble getting the sound from the 'Vinyl Ripper' application (U-RIP 22 interface) to the computer speakers.
The sound tracks appear in the sound level visualisation indicators, but no sound from the speakers. The tracks record on the hard disc for editing later. It would be helpful to hear the tracks as they are being played.
The computer is the Apple MacBook Pro with the Lion version 10.7.3 operating system.
Many thanks for any help.
Cheers, Steve.
