Concretely? What settings do you use for jackd or jackdbus? What audio device/s do you use? What kernel do you use? What boot options do you use? Are you using external MIDI gear? The output of of cat /etc/security/limits.conf;printf "\n\n---\n\n";cat /etc/security/limits.d/audio.conf should return @audio - rtprio 99 @audio - memlock unlimited a rtprio less than 99 most of the times is idiotic. Post the output of the above commands and of arecord -l; aplay -l; amidi -l also that of /etc/init.d/rtirq status Nothing should share an irq with your sound card. Assumed something should do so, then if possible, you need to unbind this device. Do not use pulseaudio! Post the output of uname -rm and cat /boot/grub/grub.cfg resp. reduce it to the 16.04 related lines. If you are using another bootloader post those boot options. Assumed you're still using a fstab, then post the output of cat /etc/fstab otherwise post the output of the mount options of your systemd settings. Consider to use noatime for audio partitions. Post the output of cat /etc/default/rtirq the output of cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor must return performance or "no such file or directory". If it returns something different than run echo performance|sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor and check again. If it returns "no such file or directory" we need to take a look at the kernel config.
