Keep getting xruns no matter what

[pkslot]

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:

Code: Select all

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

And got this:

Code: Select all

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

This step isn't necesarry, you can also leave it to default or select hw:0.
Which version of QjackCtl are you using? Does it also happen when you click OK instead of Save?

I posted this in my terminal:

Code: Select all

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

Try

Code: Select all

jackd -d alsa hw:SB

I posted this in my terminal:

Code: Select all

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

Try

Code: Select all

jackd -d alsa hw:SB

It gives me this in the terminal:

Code: Select all

Looks good to me! Except for the xruns of course. I now see you're using Jack2. You might want to try the -S (synchronous) option:

Code: Select all

jackd -S -d alsa hw:SB

You can add this switch to the Server Prefix field in QjackCtl so that it says /usr/bin/jackd -S (or just add -S to the Server Suffix field if you're using QjackCtl 0.3.9).
