Please install the version of jackd2 in the Ubuntu Studio Backports PPA
found at https://launchpad.net/~ubuntustudio-
ppa/+archive/ubuntu/backports/+packages to see if that fixes the
problem. If it does, then I might be able to set-up a Stable Release
Update (SRU) to get it into 20.04.
Setting as "Incomplete" for now simply to ensure a response happens in
the next 60 days or this bug expires since this is critical to
troubleshooting this problem.

Title:
jackdbus produces high cpu load
Status in jackd2 package in Ubuntu:
Incomplete
Bug description:
if jackd and jackdbus run, jackd and/or jackdbus produce high cpu
load. jackd tends to take all availabl CPU power bringing the system
to slow down remarkably. Killing jackd and jackdbus frees cpu and
system load drops from 100%/per CPU down to ~4% overall.
