I've tried all of the following in the listed order but nothing's changed: I've hunted and hunted all over the internet trying all various suggestions that others have had success with - I've tried all of the following, but still no luck: 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.
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.
