Yes, sound comes out of the speakers on the HMX when I use audemo.

When I try to get sound from say, Flash, RealAudio or other programs
that I know make sounds, no sound comes out of the speakers on the HMX. 
In the case of Flash, the program runs but now sound comes out of the
speakers.  In the case of RealAudio I get an error that I am unable to
reproduce from home with VNC, something about audio device is in use by
another program though.
