$ mplayer -ao alsa -af volume=-5 -softvol -softvol-max 100 as.mp3 &

# MPlayer 1.0rc2-4.1.1 (C) 2000-2007 MPlayer Team
CPU: ARM

Playing as.mp3.
Audio file file format detected.
Clip info:
Title: As Long as You Love Me
Artist: Backstreet Boys
Album: The Hits: Chapter One [Canada 
Year: 2001
Comment:                             
Track: 3
Genre: Dance
==========================================================================
Forced audio codec: mad
Opening audio decoder: [libmad] libmad mpeg audio decoder
AUDIO: 48000 Hz, 2 ch, s16le, 320.0 kbit/20.83% (ratio: 40000->192000)
Selected audio codec: [mad] afm: libmad (libMAD MPEG layer 1-2-3)
==========================================================================
AO: [alsa] 44100Hz 2ch s16le (2 bytes per sample)

!!!! Here while wait a long time, then play the music !!!!



And then two mplayer processes run:
$ ps
658 root 10192 S < mplayer -ao alsa -af volume=-5 -softvol -softvol-max
660 root 9808  S < mplayer -ao alsa -af volume=-5 -softvol -softvol-max

Why there's two mplayer processes run if I run with "alsa" ? 

And I used -srate 48000 before, but the effect is also bad. Can you tell
me which command I can use to play this music for better effect and DO
NOT need wait a long time or setup double processes?


Thanks
