I don't no if it would help, but some people claim, that using a value
for "nice" for PAM should help, when there are issues regarding to the
GUIs. I wonder if "nice" has any effect to real-time, but perhaps it has

It couldn't harm to test if editing /etc/security/limits.conf ... for my
distro it's /etc/security/limits.d/audio.conf ... should improve
something.
