I feel really stupid, but after hours of searching, I'm really lost. No
idea what I'm missing.
New computer - new install of Kubuntu 20.04 - no sound.
I thought it might be a hardware problem since it's a new computer, but
when I boot to a LiveDVD of the same distro, everything is fine.
When I connect a Bluetooth speaker, it's recognized and works.
