problem accessing raw1394 device as a normal user

00l0 · 2009-07-11 17:37:30

hello,
i have already posted my problem as a reply in this topic: http://bbs.archlinux.org/viewtopic.php?id=47723, howver i'm not suer what section it would really fit in so and the solution i believe the solution is trivial so i sort of duplicate it here...I hope there is no problem.

Well, the problem is that i cannot start jackd -d firewire as a normal user, as root tho, there is no problem and i have tried to play audio files through jack using mplayer w/o any problem... I own a Focusrite Saffire and have installed FFADO libraries.

Error output:

Should I change udev rules group to audio? How do I do that in Archlinux? :$

$ ls -l /dev/raw1394
crwxrw-rw- 1 root video 171, 0 2009-07-12 14:31 /dev/raw1394

$ groups
network video audio optical storage users

I think it's some sort of permission problem....Any suggestion is welcome! thank you!

Try adding your user to the video group, since that's the owner of the device.
