Yes, it does, through the headphone

Well ... this is a very good one: while perusing 'man mplayer' I
dicovered an option I'd never used; started to play with it and finally,
putting this line in /etc/mplayer/mplayer.conf:
ao=alsa:noblock:device=hw=1.0
I was able to ear sound coming out of my usb speaker!!!!! ;-)
Unfortunately, other players (e.g. sound-juicer, realplayer) do not have
a similar option, AFAIK, and the usb-speaker remains mute for them.
Maybe this info can be of some utility to understand what happens?
Anyway, thanks for your help.
Reagrds,
