WaveArtist：源码内容
  2.  (the following is from the armlinux CVS)
  4.  WaveArtist mixer and volume levels can be accessed via these commands:
  6.   nn30 read registers nn, where nn = 00 - 09 for mixer settings
  7.                               0a - 13 for channel volumes
  8.   mm31 write the volume setting in pairs, where mm = (nn - 10) / 2
  9.   rr32 write the mixer settings in pairs, where rr = nn/2
  10.   xx33 reset all settings to default
  11.   0y34 select mono source, y=0 = left, y=1 = right
