I'm missing something here - other than adding 2 lines
to /etc/security/limits.conf what other terminal black magic is needed
in order to run a fairly general (DAW + synths) linux audio environment?

it's more a case of 'endless iterative tweaking'

I for one have had issues with xruns since upgrading Jack and Ubuntu (I know, don't say it)
and certain apps cause xruns in differing amounts
Yoshimi is unusable VLC still a problem, while Ardour, Phasex and Pd seem less problematic
haven't tested all my audio apps on my laptop but...

I have spent way, way too much time tweaking
/etc/security/limits.conf && /etc/security/audio.conf
plus messing around with the priority/frames settings in Jack
this is not a 'set and forget' sort of thing (for me at least)
since params live in multiple places and are non-orthogonal - it's been like playing whack-a-mole

there are some docs online which walk one through the process of optimizing a system for audio and setting up Jack but so far I'm still not able to arrive at a combination of settings that bring my system to xruns=0
