As xwax requires you to have relevant hardware, here's a workaround to try if "rtprio" works for you:
1) sudo apt install jackd1 2) add "@audio - rtprio 99" to /etc/security/limits somewhere 3) make sure you're in the audio group 4) new login/shell 5) run "jackd -d alsa" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873315 Title: 5.4.0-24.28 does not seem to apply rtprio, whereas -21 does.
