Something you can also try is using a different jack on your computer, if available. If you can hear audio correctly, then the issue is indeed on your own Windows 10 device.
Plug your device into the audio jack of a different computer, laptop, or even a smartphone. If your headphones or speakers have a hardware fault, there is no need to try and fix the issue within Windows. The very first thing you should do is identify what type of issue you’re dealing with.
