Getting into Music and Audio

So i’ve installed Jack and it seems to be running. I added permissions for it according to Unfa’s (the guy in the video above) manjaro setup video. However, I get the following error when I start Ardour. Is there something I need to add to remove that error?

"WARNING: Your system has a limit for maximum amount of locked memory. This might cause Ardour to run out of memory before your system runs out of memory.

You can view the memory limit with ‘ulimit -l’, and it is normally controlled by /etc/security/limits.conf"
