I'm running Juno. I've been getting a lot of noise out of my microphone, so I followed the typical steps to edit
/etc/pulse/default.pa and added this:
load-module module-echo-cancel source_name=noechosource sink_name=noechosink set-default-source noechosource set-default-sink noechosink
...And then did
pulseaudio -k to restart. When I did this, the audio devices are of course properly added... But when I go into the Sound in System Settings, the app crashes. Pulse Audio Volume Control (which is far more versatile) does not.
When running it from terminal, I can see it seems to just hard segfault:
fish: “io.elementary.switchboard” terminated by signal SIGSEGV (Address boundary error)
Is this simply a bug or some configuration problem on my part? Thanks!
