Speaker popping through projector

[Robert741]

Why do speakers pop and crackle when connected to projector?

 

[Krishan Mourya]

That may be because of a bad wire or bad Audio Port. Usually if you are using speakers with audio cards or on-board audios of poor quality then interferences occur which cause such crackles. Make sure there arent so many devices around the speaker as they can also cause disturbances.
