Public bug reported:

I want to report the situation, because I use my laptop to teach music
to my students with midi keyboard.

In the past I use QjackCtl or Cadence (pulseaudio bridge off) on my
laptop, I can run jackd2 on 128X3 buffers with forced 16 bit to use
Qsynth and Hydrogen well without Xruns ,but I get lot of  xrun on
Ubuntustudio 20.04 (the same laptop, and using recommended system
tweaks., The sound becomes distorted.  The version of ubuntustudio-
controls is 1.12.3 .  On "Pulse Bridging"tab , Even I turned off all
input bridge and output bridge ,and it still happen. I found pulseaudio
is still working (I can hear sound from normal apps like Firefox... ).

I see  an option "turn on a2jmidid", but no "turn on  Pulseaudio
Bridge" option. In pro audio job ,we usually only use full jack audio
system. (Using pulseaudio during break time). I wish there is an option
"turn on  Pulseaudio  Bridge" ,so I can turn off it.
