Title:
  AudioFirePre8, MIDI data from hardware port is invalid when MIDI
  playback runs at 88.2 and 96.0 kHz

Status in libffado package in Ubuntu:
  Incomplete

Bug description:
  I confirm this bug with my AudioFirePre8.

  I generate this bug in the way below:
  1.Prepare reliable MIDI capture device. I utilize E-MU 0404 USB with snd-usb-audio.ko (ALSA).
  2.Connect hardware MIDI-out of AudioFirePre8 and hardware MIDI-in port of E-MU 0404 USB
  3.Prepare reliable MIDI playback and capture software. I utilize "kmidimon" for playback and "amidi" for capture.
    Using "kmidimon" and "a2j" togather, software MIDI playback port is connected to jackd's MIDI subsystem.
    "amidi" can directly listen to hardware MIDI-in port of EMU 0404 USB with ALSA's MIDI subsystem.
  4.Run jackd with Firewire backend at 88.2 or 96.0kHz and connect necessary ports.
    See "connection.png".
  5.Playback MIDI events to AudioFirePre8 and capture it from E-MU 0404 USB.
    I use "control.mid" as playback MIDI data. It includes control change events of 00 control in channel 1.
    The captured data is converted to text data, result_XXXX.log.
  6.Compare playback and capture MIDI bytes.

  When MIDI playback runs at 44.1 and 48.0 kHz, the capture data is the
  same as the playback but they are different at 88.2 and 96.0kHz.

  And at 88.2 and 96kHz, the capture data varies in each playback.

  This bug also appear in current upstream, svn revision 2299.
