Public bug reported:
Installation details:
Ubuntu 19.04

Installed: 1.0.25+dfsg-0ubuntu5

Expected behaviour:
Expected a 'Speaker - Built-in Audio' option in my Audio settings.
Actual behaviour:
Seems the 'Speakers - Built-in Audio' playback device is not available in my
settings. Instead there is 'Headphones - Built-in Audio' which obviously
shouldn't exist.
When actual headphones are attached, the do not playback either.
Playback only works when connected via bluetooth or HDMI, but there are
extra options, that do not work... not sure what it is detecting, as
there is only one HDMI output.
I followed this document to debug myself:
https://help.ubuntu.com/community/SoundTroubleshooting.
However, the second step works fine when connected via bluetooth or HDMI, as
stated before.
I have tried booting the Live USB, and audio works perfectly fine here,
so this is not a hardware issue.
