Available PCM drivers:
  alsa alsa=PLUGIN:CARD,DEV,SUBDEV
    Advanced Linux Sound Architecture PCM driver, using
    ALSA 1.0.13.
    The device specification follows the ALSA device naming
    conventions, a detailed description of which is available
    at the project's website:
        http://alsa-project.org/alsa-doc/alsa-lib/pcm.html
    Various ALSA plugins can be used here, 'hw' allows direct
    adressing of hardware channels by card, device and subdevice.
      PLUGIN - the ALSA plugin, 'default' is usually good enough
      CARD   - the card number for plugins like 'hw'
      DEV    - the device number for plugins like 'hw'
      SUBDEV - the subdevice number for plugins like 'hw'
    Devices (Solo1 - ESS ES1938 (Solo-1) rev 0, irq 10):
   >        hw:0,0 (subdevices: 2*playback (1 busy) + 1*capture)
  oss oss=DEVICE,MODE
    Open Sound System PCM driver:
      DEVICE - PCM device file name
      MODE   - may contain "rw", "ro" or "wo" for
               read-only, read-write or write-only access;
               adding "hs" forces hard sync on underruns.
    Error: No devices found
  null
    Discard all PCM output and provide zero blocks as input. This
    driver is not part of the automatic PCM device selection list.
  auto
    Auto is a special driver, it acts as a placeholder for
    automatic driver selection.

Available MIDI drivers:
  alsa alsa=PLUGIN:CARD,DEV,SUBDEV
    Advanced Linux Sound Architecture MIDI driver, using
    ALSA 1.0.13.

   >        hw:0,0 (subdevices: 1*input + 1*output)
  oss oss=DEVICE,MODE
    Open Sound System MIDI driver:
      DEVICE - MIDI device file name.
      MODE   - one of "ro", "rw" or "wo" for
               read-only, read-write or write-only access.
    Devices:
   >        /dev/midi (read-write)
