TIL: Configure Pulseaudio to not switch output to hot-plugged devices

Motivation

I have Blue Yeti USB microphone which also has an audio output for monitoring. I do not use the output but once pluged-in - Ubuntu recognize it as new sound card and switch output to the microphone immediatelly. This drives me nuts because I always need to switch back audio output manually to previous device.

Pulseaudio config

Pulseaudio has a feature automatically switch to hot-plugged devices which is enabled by default. All is needed - comment out this setting on the configuration.

Find and remove or comment-out the following lines on /etc/pulse/default.pa file:

### Use hot-plugged devices like Bluetooth or USB automatically (LP: #1702794)
.ifexists module-switch-on-connect.so
load-module module-switch-on-connect
.endif
