Hi Takashi,
Today I finally had some time to try your patches. I have a Terratec Phase
24FW Card. I did use the latest version (as of today) from
https://github.com/takaswie/snd-firewire-improve.git on a Debian testing
system. I did not use dkms but loaded the driver manually:
$ cd sound/firewire
$ modprobe -r snd-firewire-lib
$ insmod ./snd-firewire-lib.ko
$ insmod ./bebob/snd-bebob.ko
First I have to say the driver does work and I can play music through the
device, so thanks for your work.
Unfortunately I managed to crash my system with it. I was using mplayer2 to
play sound files and it seems that if I let mplayer2 play multiple files the
system crashed somewhere between the end of the last file and the start of the
new file (probably a race or something). I only did some quick testes because
I hat to reboot after every crash (even sysrq doesn't work anymore), but I
think the crash doesn't happen every time mplayer2 switches to the next file,
but most of the time. If I let it play only one file I didn't observe any
crashes.
Here is the mplayer2 command I did use for testing:
$ mplayer -ao alsa:device=hw=1 <some files>
And here the output of /proc/asound/cardX/#XXX

Now, my experience:
I am testing on a new, well provisioned PC, freshly loaded with Ubuntu 13.10. My firewire card has a Texas Instruments chipset, and my device is the Ozonic. I install via DKMS, as per your instructions, and then sudo modprobe snd-bebob. The snd_firewire_lib and snd_bebob modules are now listed in the output of lsmod. The device has installed as card2 (hw:2,0). I can now test MIDI input with:
$ amidi -p hw:2,0,0 -d
... which satisfies me that all MIDI output from the various controllers on the Ozonic is being received. I have not yet tried to send any MIDI data to the device.
I open Audacity, which now lists "Ozonic: Ozonic PCM (hw:2,0)" as ALSA input and output options. However, no audio input is shown when I try to monitor the audio input, and trying to play generated audio (e.g. DTMF tones) results in the message: "Error while opening sound device. Please check the output device settings and the project sample rate." I have repeated the experiment at all supported sampling rates (44100, 48000, 88200 & 96000 Hz), and obtained the same result in each case. I then close Audacity and try:
$aplay -D hw:2,0 test.wav
(where test.wav has been saved from Audacity)
... and this responds with:
aplay: main:722: audio open error: Input/output error
Based on my experiences with the Ozonic under FFADO, I might easily have resigned myself to thinking that full functionality will only be apparent once a mixer is implemented. I had hacked together the "unmute-ozonic" utility under FFADO in order to overcome the need the need to dual boot in order to get I/O. However, the fact that an error message is returned upon trying to open the Ozonic's output makes me think that this is another problem entirely.
UPDATE: I have just this moment been able to do the following:
$ aplay -D hw:2,0 Desktop/test.wav
Playing WAVE 'Desktop/test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono
aplay: set_params:1239: Channels count not available
... which appears in order to me, except that no audio can be heard. I assume this is due to the lack of a mixer. I will retrace my steps to try and figure out why it is now apparently working. However, I now open Audacity again, and the first thing I notice is that my pass-through audio immediately disappears (I have a sound source playing into the unbalanced inputs throughout). Audacity responds exactly the same as before. I close Audacity and aplay can no longer open hw:2,0 (I/O error as before). Now I modprobe -r the modules (and lsmod to confirm they're gone), cycle the Ozonic's power off and on, and the audio pass-through has reappeared! I also see that lsmod lists both snd_firewire_lib & snd_bebob as having reloaded themselves automatically.
My testing is probably not particularly rigorous, and I would sincerely appreciate your advice on what steps to follow in order to verify your driver's functionality. In particular, you mention "(to control mixer channels please use FFADO upstream)". I have not yet set up FFADO on this machine, but I also see under "Note":
"- Don't use simultaneously 'ALSA PCM/MIDI playback/capture' and 'jackd with Firewire (FFADO) backend'. Both of them try connecting to the device when another is running." Would you please explain? How should one rely on the "upstream" mixer functionality while keeping jackd out of ALSA's way?
Once again, thank you sincerely for doing this. I, for one, feel like a kid on Christmas Eve!
Kind regards,
Mark Brand.

Subject: [FFADO-devel] Call for testing: ALSA driver for Fireworks/BeBoB based devices
Hi all,
This is a call for testing my ALSA driver for Fireworks/BeBoB based devices.
Please test 'snd-fireworks' for Fireworks and 'snd-bebob' for BeBoB if
you have some devices listed in the end of this mail.
