Toggle on the following options: Allow app to access your microphone and Allow desktop app to access your microphone (if you launch PowerPoint directly from your desktop app).

Under Input devices, select the device you want to enable and set as your default device. Additionally, you can hit the Troubleshoot button to find and fix problems with recording sound.
Reason 3: If you are adding audio in the second way (inserting audio file), you may insert wrong even corrupted files by accident. You may hardly know which audio file is supported by Microsoft for making eligible video by adding audio so that you put the unreadable audio format. Moreover, the corrupted file happens due to a bug or defect in your software.
