Hi Takashi

I am testing your FFADO and ALSA drivers for a ProjectMix I/O.  My goal is
to get the hardware running in Ardour3 with both a firewire interface and
MIDI controls working.  I hope this is possible presently.

My configuration:
Ubuntu 14.04 (recently upgraded to get kernel 3.13 for your ALSA driver)
Installed the 3.11 firewire ALSA driver and the latest SVN FFADO driver
I have disabled PulseAudio as described

Your ffado-mixer opens and recognizes the ProjectMix, but I am not able to
see any reaction to the ffado-mixer sliders on the ProjectMix hardware.

I installed the modules with dkms.  ALSA appears to identify the ProjectMix
but I am not able to route sound through aplay or arecord.  I am not able to
verify MIDI to or from the ProjectMix.

Output: aplay -l

Output: /proc/asound/card1/firewire/clock

Output: /proc/asound/card1/firewire/firmware

Output: /proc/asound/card1/formation

Output: /proc/asound/card1/firewire/meter

Output: /proc/asound/card1/midi0

Output: /proc/asound/card1/pcm0c/info

Results of aplay -D hw:ProjectMix test.wav:

arecord -D hw:ProjectMix -c 8

arecord -D hw:ProjectMix -c 8 -f S32_LE

arecord -D hw:ProjectMix -c 8 -f S32_LE -r 8000

arecord -D hw:ProjectMix -c 8 -f S32_LE -r 48000

In addition to PCM streaming, I have tried monitoring the ProjectMix for
MIDI events using gmidimonitor:

gmidimonitor did not generate any midi events.

I would appreciate any help you can give me.
