Bug Description

This is 18.04 LTS but also occurred in 16.04 LTS. I have gone through the troubleshooting steps here:

https://help.ubuntu.com/community/SoundTroubleshooting

and have included some output of those diagnostic steps below:

$ sudo aplay -l
aplay: device_list:270: no soundcards found...
