If you've tossed the owner's manual to your microwave, check the manufacturer's website. It could be a button combination or, like on some microwaves, be buried in a submenu that's not at all obvious how to activate. Even if you don't have a Sound button, there's no Mute function denoted as a secondary function and holding a button doesn't do anything, there is still a chance a mute function exists. If none of these work, it's probably best to consult the manual. (Child lock doesn't actually lock the door, but instead locks the control panel so no buttons can be pressed until the lock is removed by holding the button for around three seconds again.) Often, pressing and holding 1, 0, Stop or Cancel will either result in turning off the beeping sounds or activating a child lock feature. Like 1 or 0, this key might have a hidden function when held. Press and hold the Stop or Cancel button.
Sometimes manufacturers give these keys hidden, secondary functions. It may have been there all along, begging you to press it. The mute function may be labeled as a secondary function of one of the standard buttons. To mute your microwave, start by checking the control panel.
