What the independent test changes
If DeviceOK passes
If DeviceOK audio is audible, the output device itself can reproduce browser audio; Zoom selection/mixing is more likely than total speaker failure.
If DeviceOK fails
If no DeviceOK audio is audible, troubleshoot system output, mute/volume, cable/Bluetooth connection and the speaker/headset before Zoom.
Check these in order
- 1
Run the DeviceOK left/right speaker test at a safe volume.
- 2
In Zoom Audio settings, choose the intended speaker/headset.
- 3
Use Zoom's Test speaker and switch outputs if the ringtone is not heard.
- 4
Check system volume, physical headset controls and Bluetooth output routing.
Retest instead of guessing
After changing one setting, run the independent DeviceOK test again before moving to a more invasive step. This preserves evidence and avoids changing multiple variables at once.
