Closed issue by VoidDuck on void-packages repository

https://github.com/void-linux/void-packages/issues/20051

Description:
Hello,

I tried many different settings but I definitely cannot get jack to run with realtime priority on Void, while it works fine on other distributions.

I checked everything described on https://jackaudio.org/faq/linux_rt_config.html and https://github.com/jackaudio/jackaudio.github.com/wiki/Cgroups but it still does not work.

Here is what I get when running `jackd -R -d alsa`:

> JACK server starting in realtime mode with priority 10
> self-connect-mode is "Don't restrict self connect requests"
> Cannot lock down 82280346 byte memory area (Cannot allocate memory)
