[Solved] Static noise with ALSA, Pulseaudio and JACK

Hi,

I'm trying to figure out how to set up jack2 correctly. If I play audio via aplay or firefox, I get a static noise. I followed https://wiki.archlinux.org/index.php/JA … ection_Kit and tried to set it up with qjackctl and cadence. My user is in the audio and realtime group.
I have no external sound card connected.

At the moment, the configuration looks like this:

If somebody can spot what I did wrong, I'd really much appreciate it! And I can provide further configs/logs if required.

Thanks in advance!

Solution
After fiddling with it for hours, I finally managed it after I posted this question. It seems my soundcard can't handle such a low latency, I set the Frames/Period to 256 and the Periods/Buffer to 4. This configuration works and I don't get any XRUNS anymore!
