Thank you Zheng Huan.
   But every time I use paplay to play a media file, it always says: Faile
   d to open file xxx
   And I found PulseAudio Daemon is running:
   moblin    2632  0.8  0.3  98060  3216 ?        Ssl  May17  25:22 /usr/b
   in/pulseaudio --start --log-target=syslog
   Any clue for me?
