The video on the SD card of the Xiaomi Smart Camera has sound when viewed on a phone but no sound when viewed on a computer

If the video on the storage card has sound when viewed on a phone but no sound when viewed on a computer, please refer to the following troubleshooting steps:
1. Ensure the computer's volume is not muted and is set to an appropriate level. Make sure the audio output device (e.g., speakers or headphones) is properly connected and functioning;
2. Check for available updates for audio drivers and apply them;
3. Try using a different video player to open the file;
4. The video file uses an incompatible audio codec. Try using a video conversion tool to convert the video to a different format and see if it resolves the issue;
5. Ensure the video file is not corrupted. Try copying the video file from the storage card to the computer again and then play it;
6. Ensure the operating system and all related software are updated to the latest versions, as updates can fix known bugs and compatibility issues.
