ZOOM and HDMI from laptop to big screen AUDIO question

[mr_lebowski]

3. The answer is one of the two above ...

But it's more likely the issue is in the Zoom options. It has its own default audio device which can (and often is) different from the default device on the machine (it overrides the default for it's own purposes). It will typically default to the laptop's speakers and headphone jack.

Which can be very handy at times, other times it can be a drag.

It's also possible Zoom changed the default sound out on the PC itself, but less likely as it wouldn't need to because it has it's own override.

And to answer you last question, NO a presenter could not do that themselves ... they can't change your zoom audio settings from afar like that.
