WebEx Recorder and Player Thinapp not playing audio

I created a Thinapp for WebEX Recorder and Player and it functions fine when executed on a physical PC, but there is no audio when played back on a virtual machine.

The VM is an XP SP3

The audio on this machine is functioning properly under normal circumstances.  Just not with the VM

I'm currently testing if the fat client of the WebEX recorder and player functions fine with the VM.
