I have a MacPro. Lately there is a buzzing sound when I listen to videos or movies or conferencing calls. How do I correct this?

Reset PRAM: Reset NVRAM or PRAM on your Mac - Apple Support

Settings that can be stored in NVRAM include sound volume, display resolution, startup-disk selection, time zone, and recent kernel panic information. The settings stored in NVRAM depend on your Mac and the devices that you're using with your Mac.

If this step doesn’t help, please contact Apple Support.
