Neil,

Please start a new thread and do not tail onto someone else’s thread for a 
different subject.

Hi All,
I recently upgraded to version 20.04 and have hit a problem with jackd and
real time scheduling. I see the output below in syslog
I know there have been kernel changes relating to this and I have seen talk
of using cgroups etc. I'm wondering if I should just go for a fresh install
but if anyone has any suggestions please let me know before I do that

Jul 29 12:28:08 housemartin pulseaudio[6970]: JACK error >Cannot use
real-time scheduling (RR/5)(1: Operation not permitted)<
Jul 29 12:28:08 housemartin pulseaudio[6970]: JACK error
>JackClient::AcquireSelfRealTime error<

Regards
