Try these Windows checks first:
- Open Start and search for Sound settings.
- Under System > Sound, in Choose where to play sound, make sure the correct speaker or headphones are selected.
- Next to Volume, make sure the speaker is not muted.
- If the device is not listed, select Add device and pair or connect it.
- If the speaker or headset is wireless, make sure it is charged and connected.
- If it is wired, unplug it and plug it back in.
If the sound still does not work:
- In Settings > System > Sound, scroll to Advanced.
- Run the sound troubleshooter from Output devices or All sound devices under Troubleshoot common sound problems.
- Open the Sound Control Panel and check that at least one speaker or headphone device is enabled.
- If using a USB hub, connect the audio device directly to the PC instead.
If Zoom is open, also verify Zoom is using the correct output device in its own audio settings.
