Careful using this - I lost audio output and was unable to restore it

Sound output in Ubuntu 18.04 LTS suddenly only contained 'Dummy Output'
Spent several hours trying to get linux to redetect the laptop sound, but gave up in the end 😞

Wow, that's weird.

I've just tested it on Ubuntu 19.10, installation:

sudo apt install mumble mumble-server
sudo systemctl stop mumble-server.service
sudo systemctl disable mumble-server.service

You can always reset PulseAudio with pulseaudio -k. I added set -uo pipefail to the script to hopefully prevent such failures.

I also increased wait time, as Mumble takes a long time to launch when using Wayland. But otherwise it worked fine.

It's weird to see 'Dummy Output' here, as it's added if you run pactl load-module module-null-sink with default settings. But the only place in the script where module-null-sink is loaded is:

mic_over_mumble/mic_over_mumble

Lines 82 to 87 in 9df955f

	function add_sink () {
	pactl load-module \
	module-null-sink \
	sink_name="Loopback_of_Mumble" \
	sink_properties=device.description="Loopback_of_Mumble"
	}

Can it be that the script somehow got corrupted (e.g. by copying and pasting it on Windows, which would insert BOM and CLRF invisible characters)?

This happens to me also. I have to manually do pulseaudio --start. Even if I get PA back up, I am unable to see the virtual mic in pavucontrol.

Even if I increase wait times, it still ends up crashing PA, making one restart it manually..
