I recently switched from DisplayPort to HDMI for connecting my computer to my display. Generally, the audio works fine via the built-in speakers in the monitor via HDMI but after the computer goes to sleep it no longer works. I have checked the Sound settings and there are no output devices listed. Any ideas?
This occurs on Ubuntu 18.10 and I upgraded to 19.04 today and the issue persists.
