Rich Sound not adequate in running this OS

Rich Sound not adequate in running this OS

The sound coming out from our WYSE V10L WTOS 800 thin client is inaudible, sounds like it is in slow motion. The Wyse client is logged in using RDP to a VMWare Host EXSi 4.1 platform and the WYSE cleint is setup as a virtualized PC. Everything else work except the sound is unacceptable. I tried to install TCX Rich Sound Client and the TCX suite but that did not help. I noticed an error on the installation menu of the TCX suite-"Rich Sound not adequate in running in this OS". We installed windows 7 32bit OS on the virtual Client PC. According to the System Information in the Connect Manager, Memory Size=458752K and Free=319658K, How can I resolve this sound issue? I will apprecial all the help I can get.
