macbook pro no audio on internal speakers or headphones

When I tried to turn the volume up, the onscreen icon indicated that they were broken, but when I plugged in headphones, everything worked fine.Īfter a bit of research, I learned about the headphone port switch, and deduced that it had become stuck. The Sound of Silence - A few months ago, my MacBook Pro’s internal speakers stopped working. That seems like a sensible design decision, but at least on a computer, it’s flawed, as my examples demonstrate. Remove the plug and the switch flips the internal speakers back on. Plug in your headphones and the switch triggers, shuts off the Mac’s internal speakers, and outputs sound to your headphones. The source of the problem, as Chris Breen once explained in Macworld, is that inside every Mac’s headphone port is a small sensor switch that detects when you insert a plug. I’ve owned dozens, maybe even hundreds, of devices with such a port, dating back to the 1980s, and have never had a problem with one, except for my two Macs: a 2011 MacBook Pro and a brand-new iMac with Retina 5K display. But they all have one common part that has given me more trouble than any other: the blasted 3.5 mm headphone port. #1661: Mimestream app for Gmail, auto-post WordPress headlines to Twitter and Mastodon, My Photo Stream shutting downĪpple has the most beautiful, well-designed lineup of desktop and laptop computers ever made.#1662: New Macs, 12 top OS features for 2023, vertical tabs in Web browsers, watchOS 9.5.1.#1663: Exploring the Apple Vision Pro, 12 more OS features coming in 2023, new Apple service features, Apollo shuts down.
