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). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1716092 Title: Enabling Auto switching streams on new active output causes pulseaudio to crash Status in pulseaudio package in Ubuntu: Incomplete 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.
