Question regarding audio out

[Lacrosse]

I come from an ATT TP2 where there was no 3.5mm jack, the audio came out of the extusb port on the bottom via the HTC dongle with a 3.5mm on it.

My question is, since the Evo has a 3.5mm jack on top, can anyone with the Evo and the HTC dongle (maybe from a previous device) try to see if audio also comes out of the usb port? I currently have my TP2 set up in my car where its just the usb for power and audio out, and if the Evo can't do this i'll have to use two wires and reroute some things.
