What ever you think might be helpful to let us know ... > 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.
