I believe the duplicate is incorrect, as that seems to be another issue.
I have had the same problem described on my laptop (a Dell XPS 13). The
fact that a force-reload works points to an audio device blocking issue,
and indeed that seems to be the case [1]. Timidity seems to cause this
problem, probably it is starting at the same time alsa tries to capture
the audio device.
The work-around solution for end-users is easy (you'll loose the
timidity service, I did not need it):
`sudo systemctl stop timidity`
`sudo systemctl disable timidity`
For an actual distro fix: perhaps the Ubuntu start-up scripts can be
reviewed and the order adjusted, as that's likely the culprit.
