How to undo 'sudo killall pulseaudio'?

Question

I ran the command

sudo killall pulseaudio

because I read it here:

Cannot pair my beats 3 bluetooth headset with Ubuntu 16.04 LTS

Now my sound doesn't work at all, when it was working before I ran this command. How do I fix it?

Answer 1

Restarting the computer worked.

Answer 2

This command should do.

$ pulseaudio -k

On the other hand, I created a simple bash script that would fix my sound when something wrong occur. This works on Lubuntu 16.04 LTS

#! /bin/bash

# removing pavucontrol config
cd ~/ && rm pavucontrol.ini && echo 'DONE: Removing pavucontrol.ini' || echo "FAILED: Removing pavucontrol.ini"

# removing pulse config
cd .config/ && rm -rf pulse/ && echo 'DONE: Removing pulse directory' || echo "FAILED: Removing pulse directory"

# restart pulse and alsa services
echo 'pulseaudio -k && sudo alsa force-reload' | bash
