PS: I don't know, but real-time audio related migrating to another kernel always could make a difference. Btw. if you should use GRUB and assuming you allow GRUB to automatically generate the configuration, consider to check, if the kernel parameter 'threadirqs' is still used. I'm using syslinux. $ grep 'Arch Linux ^threadirqs' /boot/syslinux/syslinux.cfg -A3 MENU LABEL Arch Linux ^threadirqs LINUX ../vmlinuz-linux APPEND root=LABEL=s3.archlinux ro threadirqs INITRD ../intel-ucode.img,../initramfs-linux.img Apropos kernel parameters, as it turned out CONFIG_AUDIT is still important for real-time audio usage, see https://aur.archlinux.org/packages/linux-rt/#comment-702130. -- pacman -Q linux{,-rt{-cornflower,-pussytoes,,-securityink}}|cut -d\ -f2 5.2.4.arch1-1 5.2_rt1-0 5.0.21_rt16-1 5.0.19_rt11-1 4.19.59_rt24-0
