Notifications don't play sound for me in Ubuntu 20.04. I've tried it with chrome and notify-send from the command line. No alert sounds. Sounds are turned on in dconf editor (org/gnome/desktop/sound/event-sounds) and system sounds is at max volume in the sound settings, yet no sound for alerts.

I am using Ubuntu20.04 and I found that "System Sounds" has been changed. Go to Settings -> Sound -> and change the volume level for "System Sounds"
Have you tried alsamixer?
Open up Terminal, then type alsamixer and press Enter.
You will get an odd sort of panel with all your output and input devices listed across the bottom, and a vertical display of the sound levels.
Left and right arrows pan through the list of sound devices, and up and down arrows increase or decrease the sound levels.
When you're dome making adjustments, just press Esc (the escape key) to exit.
