Problems while using mplayer based on ALSA

Problems while using mplayer based on ALSA

[\x11]

Hi All:
   Im having problems  while using mplayer 1.0 to play music based on alsa 1.0.15.
  Im using an ARM9 system and montavista linux 2.6.18.
   Here's what the problem is and what's modified in the mplayer.conf:


***************************************************************************************************************

/ $ mplayer /tmp/a.wav
MPlayer 1.0rc2-4.2.0 (C) 2000-2007 MPlayer Team

 *****************************************************************************************************************
/etc/mplayer/mplayer.conf
##################
# audio settings #

# Specify default audio driver (see -ao help for a list).

# Use SDL audio driver with the esd subdriver by default.
#ao = sdl:esd
 
# Specify the mixer device.
#mixer = /dev/mixer
 
# Resample the sound to 44100Hz with the lavcresample audio filter.
#af=lavcresample=44100
****************************************************************************************************************


Can anybody tell me what going wrong with this?



Thanks in advance!

Please use the -v option when reporting problems.

Does your platform support dynamic linking and versioned symbols?
How did you configure alsa-lib?
