Dear All, 
 
I follow the steps in http://wiki.bluez.org/wiki/HOWTO/AudioDevices 
 
step 1.Install bluez-utils-3.22 with "--enable-audio" parameter.
step 2.Create ~/.asoundrc  and modify it to contain  
      pcm.bluetooth
      {
       type bluetooth
       device 00:18:6a:00:01:06
      }

step 3.mplayer -ao alsa:device=bluetooth /wulai.mp3" to play music and  meet the errors:
    alsa-lib:pcm_bluetooth.c1240:(bluetooth_init) connection fail
    alsa-init:playback open error: Connection refused
 
I do not know how to fix it,may anyone help me? Thanks very much!

Best regards,
Leiyu
