Running Linux Ubuntu 20.04 via VirtualBox but am encountering no sound.
My primary laptop does have sound but when I run Ubuntu via VirtualBox,
there is no sound. Did have sound initially when I first installed
Ubuntu but audio went out after I installed updates. Tried installing
Alsamixer and PulseAudio Volume Control but both could not fix issue.
