xv6800 Music Playing Problems

[mds1354]

I recently acquired a Verizon xv6800 WM6.1 radio 3.35.04. I am having two problems with music/sound listening. First, I cannot find how to listen to media through the external speaker (like YouTube or music). Second, I have a USB headset that works fine for phone calls, but when I play music on WMP no sound comes through the headset.

My apologies if this has been covered before...I've spent hours searching the web and the owners manual without success. Any help is much appreciated!
