Hello,
I’m quite a newbee when it comes to Linux. I’m running Ubuntu Studio for a couple of weeks now and so far I’m very impressed. Since I’m a dj for a very long time and also (very beginning amateur) producer I want to mess around with the audio applications in Ubuntu. I have been dj’ ing and producing with Reason and live…
Off course also Ardour. But when I’m trying to start it up the Jack server won’t run.
I’ve read many discussions but so far nothing helped. What I did so far:
Type in Ardour2 in the terminal, than it (sometimes) runs
Change settings in Jack (now they are as following:
Preset Name = default
Server path /usr/bin/jackd
Ticked: force 16 bit, verbose messages output)
For the rest nothing interesting I think
What I’ve done in the done in the limits.conf
tim - rtprio 99
tim - memlock 500000
tim - nice -10
this is what I’ve added after the #end of file
I tried to run jack -d alsa
And this is the output of my Jack:

That last message is a problem I’ve seen with many users. So far any of the suggestions that were helping for other users didn’t help me.
I’m by the way on a soundblaster live value 16 bit using the emu-510 (if I’m correct) driver.
I also have the latest kernel and I’m in the group for audio. Any help is more than welcome. Thanks in advance!
