title: Simple way to add line to Ubuntu bashrc
body: <p>I am just starting my journey with Ubuntu and I am having a problem getting sound from my speakers when using the line in.  I have been entering the following in the terminal every time I log in or reboot =  <code>pactl load-module module-loopback</code></p>
  
  <p>I am not familiar with editing a bashrc file so I was wondering is there a simple way to achieve it?</p>
