Audio Test Fails with 1 second sound, then no sound on Desktop

[llkondo]

Why does the audio test fail to give more than 1 second of sound on a given speaker? Yet in a zoom meeting, both the microphone and the speaker seems to work fine? This seems to be a glitch in the audio test for speakers itself. Has anyone else encountered this problem? How do you get the audio test to work properly again? Does deleting the zoom account and then restoring it back again help?
