In 'system information', when I look in sound hardware.

so it's not the optical speaker switch problem most people seem to have.

NO RED LIGHT coming from headphone jack.

checked System Preferences->Sound settings: nothing showing up under the Output or Input tabs (no 'Internal Speakers' showing up).

I see the volume no-access icon (circle with diagonal line through it) when trying to change volume.

No sound coming from output jack (headphones or external speakers).

Built-in speakers don't make any sounds.

just like I did everyday before that, but for some reason this time I didn't get any sound output and the volume feedback was delayed when I tried to turn the volume up/down. It has *not* experienced any water damage or drops, but I'm pretty sure this problem started when I plugged in my external power speakers' amp to the headphone jack. This differs on a per-app basis, but you can generally find most app preferences by clicking the app’s name in the menu bar at the top of the screen, then clicking on “Preferences.” When in doubt, a quick web search for something like “no sound mac” should yield some advice.I am really stumped by this problem, and I'm really hoping you guys can help as I'm pretty sure it's a hardware issue.īasically, I get no audio from my MacBook Pro Retina 13' Late 2013 A1502 16Gb 2.6GHz - everything else works beautifully as ever with this machine (incl USB & power) apart from the sound. The same can be said for a microphone that isn’t working when it should be.

If you have no audio at all you likely need to specify an output device (like “Internal Speakers” or “Headphones”). To rectify these problems you’ll need to dig into the app’s preferences.

This includes DAW software like Ableton, video editors like Adobe Premiere, and sound-editing software like Audacity. Some applications have their own sound preferences that must be managed manually. Not all sound problems are related to macOS. If you cannot see your HDMI device listed and it’s definitely connected and working, try disconnecting it and plugging it back in. Your Mac should remember which device output settings you prefer in the future.
