I tried "mplayer -ao plughw:0,0 file.mp3" but I got: No such audio driver 'plughw' No such audio driver '0' Could not open/initialize audio device -> no sound. Audio: no sound

Decode it user flac decoder to wave file, then downsample it. You could encode it back to mp3/ogg etc. There are many programs to do downsampling. I think even the lame/oggenc support downsampling. Otherwise install the package "samplerate-programs" and sndfile-resample -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?
