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! martin Jeremy Jongepier wrote: > On 10/30/2010 07:38 PM, mentoj dija wrote: > >> 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.
