thanks guys for all your help.
IT WORKS! after a hole weekend of frickling, about time ;-)
and that with only about 5 ms delay. much less then i expected. the
solution? downgrading to 10.04, then sleepless playing around with the
jack settings and very important: about a hundred reboots (well it felt
like hundred). thanks especially to brian. that helped me a lot!
now i have two other problems: first of all: the input level of the
channels 3-8 (mic / line) is to little. even if i turn up the volume of
all my devices to maximum, there is no cliping light flashing. the
input-level of the channels 1 and 2 (mic / instruments) is fine. is
there a solution? sry, i know, it has nothing to do with ubuntu studio
itself, but maybe you can help me anyway.
i also have a problem with an extern synthie: it produces a slightly DC,
so that the recorded wave is not in the middle (i hope you understand
what i mean). with audacity, i can easily fix it with the normalizing
funktion. but i cant find an equal funktion in ardour. the normalizing
there got no effekt to the slightly shifted 0-db-line.
nice new week!

hello list,
my firepod arrived today, hell yea!
but now, the challange to keep it running.
so i found this website
(http://ubuntuforums.org/showthread.php?t=522738) with some instructions
how to do it.
*-install a realtime kernel:* obviously there is no one in the standart
installation. so i just skiped this point. i only want to record and
dont care for long delays.
What is the output of cat /proc/interrupts ?
*- Obtain/checkfor FW lib and raw1394: *the libraw1394-11 is installed.
i'm not sure what to do with this FW lib. but i also installed the
package libfreebob0 which seemed to be important
If you want to use a FireWire soundcard you need libraw1394 which will
create a raw1394 device node. Without FFADO won't work, it needs this
device node.
*- Set permissions for raw1394 for GROUP=audio*: thats where i got
stuck now. don't know what to do. is there a file raw1394?
Install the package ubuntu-studio-controls, this tool will allow you to
set the right permissions. What it does is adding the raw1394 kernel
module to /etc/modules and it adds some lines to
/lib/udev/rules.d/50-udev-default.rules so any user of the audio group
can use the aforementioned raw1394 device node.
*- Enable/check user for group audio:* group already exists. but enable
it for what?
Your user account with which you want to use the FireWire soundcard has
to be a member of the audio group on your system.
then i filled in all these listed jack settings. i also enabled the
raw1394 access at ubuntu-studio-control. but jack is not working at all.
it stops with the message:
Cannot connect to server socket
jack server is not running or cannot be started
before i did all that i tried the firewire-driver instead of
firebob. and it worked. but with to much x-runs. so ich changed
settings and stuff, and now, its also not working with this
firewire-driver ;-)
You need the firewire driver, freebob is deprecated and only there for
legacy reasons (or a living proof of the developer's procrastination ;) )
so is there a very simple thing i have to do?
You were already mentioning downgrading to 10.04. That might not be such
a bad idea, with 10.04 you have a access to multimedia PPA's like the
ones from philip5, FalkTX and AutoStatic. Besides, 10.04 has a real-time
kernel.
Best,
Jeremy
