I have no sound

Hi,

I'm on Pavilion laptop with Windows 11 24H2.

All of a sudden, my speakers are not working for Zoom, but they work for everything else.

When I do a speaker test, the bar is flashing as normal to show that it is making sound, but nothing comes out of the speakers.

I uninstalled and re-installed the app a few times, even removed FXSound sound enhancement, but I am still not getting any sound out. 

Mic and camera work fine.

Has anyone got any suggestions please?

TIA
