[Bug 1867539] Re: pulseaudio bridge cause mass Xruns, even there is no output/input

 

We believe you are indeed having the problem. I just tested on a clean
install myself and using the same settings you did, I was unable to
reproduce the issue. Therefore, there might be some incompatible
hardware on your end. Remember, not all hardware is 100% compatible with
Linux.

Since the problem cannot be reproduced by myself or by Len (and we have
completely different hardware) it is therefore *not* a bug and therefore
this is a support request that should be on askubuntu.com, not a bug
tracker. Hence, it's closed as "Invalid" which, in Launchpad, is defined
as "Not a bug. May be a support request or spam." This is clearly not
spam, therefore it's a support request.

Please present your issue on askubuntu.com tagging "ubuntu-studio",
"jack" and "alsa". Perhaps someone there will have an idea what is going
on. Either way, this discussion does not belong on a bug tracker.

Title:
  pulseaudio bridge cause mass Xruns, even there is no output/input

Status in ubuntustudio-controls:
  Invalid
Status in ubuntustudio-controls package in Ubuntu:
  Invalid

Bug description:
  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.
