No Audio From Desktop When Remote Control From Windows Phone

[petec]

I just installed the latest TeamViewer on a Windows 8 phone and on a desktop running XP Pro.  I can use the phone to access the desktop computer and launch programs. 

If I launch a program that plays a video (with a sound track) the sound track cannot be heard on the phone even while it can be heard through the desktop speakers.

Any ideas?

Thanks In Advance,

Pete
