Bug Description

Not sure if this is a plasma-pa bug or a pulseaudio bug. In plasma-pa -> Audio Volumue -> Advanced tab.... checking the "Automatically switch all running streams when a new output becomes available" cause PA to crash. If the /etc/pulse/default.pa file is modified by commenting out following line:

  load-module module-switch-on-connect

PA will start as expected. I have not checked to see if the auto switching works when the default.pa line is commented out.

Followup: Autoswitching works perfectly even with the line "load-module module-switch-on-connect" in /etc/pulse/default.pa commented out.

If it still works commented out then it sounds like your definition of "when a new output becomes available" is covered by the similar:
  load-module module-switch-on-port-available

As for removing module-switch-on-connect, we already plan to do that in 18.04 with the introduction of PulseAudio 11 since it has better defaults which handle all the device hotplugging cases we care about (Bluetooth devices and USB DACs).

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

Now open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit.
If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'.

I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.
