If I use the following command to play the mp3 file whose sample rate is
48000, I must wait more than 20 seconds, after that mplayer play the
sound:

# mplayer -srate 41000 -af volume=-5 -softvol -softvol-max 100 as.mp3 
MPlayer 1.0rc2-4.1.1 (C) 2000-2007 MPlayer Team

Playing as.mp3.
Audio file file format detected.

==========================================================================
Forced audio codec: mad
Opening audio decoder: [libmad] libmad mpeg audio decoder

How can I solve it? I hope I can hear the sound in less than 3s.

Thanks
