Even with the realtime kernel, following the steps here: https://jackaudio.org/faq/linux_rt_config.html and setting jack to realtime (QJackCtl -> Settings -> Parameters -> Realtime, or using the jackd -R command line arg), I was getting a ton of XRUNs (visible in QJackCtl as the red number, or in the Messages dialog), making the sound stutter a lot.

Increasing the Frames/Period and Periods/Buffer made the XRUNs go away, but increased the latency to a few hundred ms.

It works on a different computer with a similar manjaro installation, so I guess it might be somewhat related to the hardware. The mainboard is a "MSI B450M Mortar Max", it's an AMD system. aplay --list-devices says Realtek ALC892, lspci -v | grep -i audio says "Starship/Matisse HD Audio Controller".


It works when I increase the Sample Rate. I have it at 88200 set now and it works really good without XRUNs and stuttering.

You can do that in QJackCtl in Setup... -> Settings -> Parameters
