ChangeSet@1.605.2.21, 2002-09-26 16:20:01+02:00, perex@pnote.perex-int.cz
  ALSA update 2002/08/05 :
    - CS46xx
      - fixed capture with new DSP firmware
      - multiple pcm playback streams
      - pcm playback instance is allocated dynamically
      - fixed detection of secondary codec
    - changed ctl/rawmidi/timer read() code to follow POSIX standard - when some data are ready, return immediately
    - RME96 - added 32 bit sample formats for ADAT
