Hi Kitchen PC,
Have you had a chance to try the steps in the AI Answer? If so, please let me know which steps you completed and whether any of them changed the popping sound.
As an additional check, try playing the same video in another browser or media player, then compare the built-in speakers with wired or Bluetooth headphones. Please also note whether the sound occurs when pausing, resuming, skipping or adjusting the volume. This can help determine whether the issue is limited to the internal speakers, a particular application, or the overall audio system.
Since this is a Dell computer, I also recommend running the speaker diagnostic in SupportAssist and checking Dell website for any available audio, chipset, BIOS or firmware updates for your exact model.
Please also share your Windows version and build by pressing Windows key + R, typing winver and pressing Enter.
Kindly update me with the results when you have a chance and I will be glad to advise further based on what you find.
