Keep getting xruns no matter what

[autostatic]

Can't guarantee that the xruns are gone, it could be something else.

Yes, this was what i was looking for. I didn't quite know where to put the sudo command. Running lsusb shows usb3 and 4 is gone. I'l just have to reboot to see what jack says about this. I hope the xrun is history

Ok, i wasn't intelligent enought to understand that i couldn't reboot without resetting the commands i just wrote.

I Still get xruns though. I'll have a look around and see if i can figure this out myself. If not, i hope i can come back once again. Thank you so much for your help

Sure, no problem! Bit of a bummer unbinding didn't work. What JACK settings do you use? Maybe the answer is way closer to home

Well, here's a print of jack, sort of running:

I set it to HW:0 cause that's the SB card, but when i set it to "default" i get a lot more xrun. Also the 1024 frames are on purpose, for the same reason.

Would it help anything, if i installed a complete realtime kernel?

[autostatic]

No. If you already get xruns without running any audio software there is probably something else that gets in the way. What are your exact JACK settings? Do you use QjackCtl? If so, what is the output of cat ~/.jackdrc ?

Yes i do, the output is:

I was having a bunch of xruns and was recommended this. If your using the ubuntu desctop install xfce or ldxe and use those to record? You could also try a different sound card I know thats not the most ideal situation but you can pic up an art dual usb pre for 59 dollars from b and h photo video. The actually sound great when i was using one I never had a problem with xruns the latency sucked but it didnt matter becuase I was just recording tracks so it didnt effect anything.

I'm currently using the gnome shell as my desktop manager, although It's configured to use lightgdm instead of gdm. When I get home I'll give xfce a spin to see if it changes anything.

I've also thought about getting an external soundcard, but using it via usb isn't really that good, regarding latency, and I haven't got any other options other than hdmi. So I'm a bit hesitant on that.... also money is kind of short at the moment. Is it possible to use hdmi instead of firewire? Or would I face more problems on that account?

Well thank you for the advice, I'll be sure to check it out.

Thanks! In QjackCtl set MIDI Driver to 'none', untick 'Unlock Memory' and set 'Port Maximum' to 256 which is afaik the default. Also fill in the 'Interface' field manually and enter hw:SB

I did all that, but somehow it seems there's nothing involving SB:

Linux is case sensitive. hw:sb is something else than hw:SB.

I can't change it, even when i edit the /.config/jack/conf.xml manually, it's changed. When i change it to capital letters in qjackctl, they change back to sb at the instance i hit save.

You should not edit jack/conf.xml manually, as it says in the file itself:

<!--
JACK settings, as persisted by D-Bus object.
You probably don't want to edit this because
it will be overwritten next time jackdbus saves.
-->

afaik the QjackCtl combo-boxes are editable, so you should be able to delete the current entry and write down a custom one.

Oops, i didn't read that

The problem is, that i can easily write in the boxes in qjackctl, but as soon as i hit "save" it changes the capital SB to sb.

I posted this in my terminal:

peter@pks:~$ jackd -d hw:SB

And got this:

Something tells me that this soundcard isn't properly installed.
