On occassion we have found that video and audio have problems in Google Chrome, this sometimes can be resolved by disabling Hardware Acceleration in Chrome.

Or other times, it just needs turning off, closing all Chrome Windows and opening Chrome and putting back on, closing all Chrome windows and it resolves the issue

To find how to do this, click on the three dots, top right


Click on Settings

Expand Advanced and then click on System

Then Toggle 'Use hardware acceleration when available'.
