i should of clarified with my sentence that i have tried thick clients view 5.1/5.2, HP thin clients. same issue. I have noticed with VMware 5.1.2 vs 5.1.1 that VMware has released a newer version of the audio driver
"5.1.1 is using driver version 6.0.0.3500" 6/30/2011
"5.1.2 is using driver version 6.0.0.3600" 10/18/2012
I am going to try and use the old driver and see what happens i will update with my results.
It is not a syncronization issue it as if the audio just cuts out (goes silent) for a second then resumes. The host and guest are under utilized in the performance metrics.
Also view connection servers are at 5.1.2
