Doug,
Then I hope you to try playback.I reccomend below process:
- use alsamixer to change sampling rate that you hope
- use jackd in usual way, or aplay with plughw interface
- hear 1/2ch or not
Alsamixer successfully changes SR and clock source. I started jack and played back and edited an ardour session with no problems. As you said earlier, capture doesn't work. the ports are there but no signal. Once that works Ill start using this driver full time.
I'm glad to hear it. I believe you can playback with any sampling rate, 32.0 - 96.0 kHz for AudioFire2, 32.0 - 192.0 kHz for AudioFire12.
But I cannot hear all of channels which I send. My AudioFirePre8 can playback 16ch (differed in current sampling rate). When I playback 16ch with aplay or jackd, I can hear only 1/2ch physical output...
I hope you to confirm this on your devices.
Currently my driver fully utilize ALSA's snd-firewire-lib.ko to transmitting (and receiving) stream. But snd-firewire-lib.ko has no codes for receiving (=PCM capturing). I'm under working for this.
Thanks

I note that your system cannot communicate to your device via FFADO because the device is already used by my module. You can execute "modprobe -r snd-fireworks" if you want to use FFADO.
That's not true. The ffado tools (the mixer, the discovery & diagnostic tools, etc) work fine whether or not the alsa module is loaded, and whether or not jack is running on the device. The problem with the AF12 and your driver was whatever the problem is with ffado and AF firmware > 4.8. Somehow the Clemens snd-fireworks driver was unaffected. I dont know enough about the driver and hardware to understand why, but I'm sure you will figure it out. I'm glad to see progress on this driver so do not hesitate to ask for anything.
