[FFADO-user] Help on using new fw stack

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi all and thank you for supporting the new firewire stack.

I'm eager to test ffado on the new stack but I seem to be missing something.

So far I have tracked these links regarding my problem:

http://www.ffado.org/?q=release/2.0.1

http://sourceforge.net/mailarchive/forum.php?thread_name=066.5b447091b7017d9ef6fd3198462a9238%40ffado.org&forum_name=ffado-devel

And I tried to follow any hint I could get out of them.

The output of my ffado-diag is:

Software Interrupts:
--------------------

=== REPORT ===
FireWire kernel drivers:

The new FireWire kernel stack is loaded. 
This stack is not supported by FFADO. Please use the old stack.
------------------------------------

Knowing that the message about the old stack is not affecting the funcionality, I continued trying to load the ffado-driver.

And I temporarily chmodded access for anyone on /dev/fw* .

# ls /dev/fw* -lah
crw-rw-rw- 1 root root  251, 0 13. Jul 18:24 /dev/fw0
crw-rw-rw- 1 root video 251, 1 13. Jul 18:24 /dev/fw1
crw-rw-rw- 1 root root  251, 2 13. Jul 18:24 /dev/fw2

However, whenever I try to run ffado, I get the old error message that there's no access to /dev/raw1394 . Although even with the new stack:

# ls /dev/raw1394 -lah
crw-rw-rw- 1 root audio 171, 0 13. Jul 18:24 /dev/raw1394

This is the output when I try to start ffado:

$ jackd -d firewire

This usually means:
 a) The device-node /dev/raw1394 doesn't exists because you don't have a
    (recognized) firewire controller.
  b) The modules needed aren't loaded. This is not in the scope of ffado but of
    your distribution, so if you have a firewire controller that should be
    supported and the modules aren't loaded, file a bug with your distributions
    bug tracker.
  c) You don't have permissions to access /dev/raw1394. 'ls -l /dev/raw1394'
    shows the device-node with its permissions, make sure you belong to the
    right group and the group is allowed to access the device.
firewire ERR: FFADO: Error creating virtual device
Cannot attach audio driver
JackServer::Open() failed with -1
no message buffer overruns
Failed to start server

Sorry if the solution to this is obvious, I just can't see it and I'd be very thankful for any help.

Best,

Gilzad
