Not-OT: IIRC there were several 5.2 and/or 5.3 kernel issues related mails on the Arch general mailing list. Arch is a rolling release, however, it provides a LTS kernel, that at the moment is at 4.19.76 and actually Ubuntu's 16.04 lowlatency is
[root@archlinux moonstudio]# systemd-nspawn apt -qq list linux-lowlatency 2>/dev/null linux-lowlatency/xenial-updates,xenial-security,now 4.4.0.165.173 amd64 [installed] Assuming the machine does use the same set-up for 16.04 and updated Ubuntu installs, my shot in the dark is a kernel regression, since the OP doesn't experience a noticeable performance issue when using the same machine, with a 16.04 lowlatency kernel and IIRC some 5.x kernels with some hardware and software are fishy.

That might explain why audio output via my LCD display always works when using Ubuntu flavour live DVDs, but never worked, if I tried to use my Ubuntu 16.04 or Arch Linux install. OTOH I used the default audio of the live DVDs, IOW most likely pulseaudio, and I used jackd from command line, when running a 16.04 or Arch session, _but_ I didn't get any jack/alsa messages mentioning an issue, there's just no audio output. I'll try to test it next week with bizarre high frame rates. -- “Awards are merely the badges of mediocrity.” ― Charles Ives -- ubuntu-studio-devel mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
