Audio problem with Aspire 5 laptop I've tried with 'enhanced sound' in the properties drop-down

I changed a while ago from an Aspire 3 to an Aspire 5. I need to use Zoom to teach music - all the sound settings worked fine on my Asp 3, but as soon as I tried to transmit on the Asp 5 the sound cut out . I use a video camera with a built-in microphone. All the Zoom settings were set up correctly for original sound. I unplugged everything from the Asp 5, reconnected the Asp 3 - all OK again, leading me to believe that there is an audio setting somewhere on the newer model which is causing the problem. I've tried with 'enhanced sound' in the properties drop-down, ticked and unticked - no difference. It sounds as if the microphone is overloading - it's the same with the inbuilt microphone array as it is with the external camera and mic. What am I missing?

Open Control Panel. Search 'sound'. Click 'change sound card settings' in left pane. Right click speaker properties. Click advanced tab. If hardware acceleration option also exists with enhancement, uncheck that too. Drop sampling rate to lowest 16bit level. Hit test button. If it sounds OK, test zoom again. If still no joy, change exclusive modes too if they exist.
