Hi John,

Thank you, I went to the site and downloaded everything (including the dependencies, to be able to build ffado) but ran into one problem: The README file says to launch the daemon, but it fails:

jackd -v -d firewire getting driver descriptor from /usr/lib/jack/jack_alsa.so getting driver descriptor from /usr/lib/jack/jack_dummy.so getting driver descriptor from /usr/lib/jack/jack_freebob.so getting driver descriptor from /usr/lib/jack/jack_oss.so jackd: unknown driver 'firewire'

I realize this is loosely related to alsa-devel, but ... Launching the qjackctl raises other issues ... when I start it, it's stopped immediately due to:

cannot create /dev/shm/jack-1000 directory (Permission denied) cannot create server sockets cannot create engine

and noticed that the only options under "Interface" setup are: hw:0, plughw:0, /dev/dsp ... but all these correspond to the built-in HDA card and not my firewire.

only one device is register as a card: cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0x9b500000 irq 20

I do have a /dev/raw1394 ... but something is not configuring it as an audio device, right?

I have a couple of machines connected to FireWire Motu devices (running OS X). We want to develop some new apps on linux and the only info I've found is: http://www.olafchrist.de/ieee1394/index.php, but its rather old and single device specific.

Are there any other solutions available? Or are there other devices (firewire) that are supported by the ALSA project?

Have you looked here? http://www.ffado.org
