Chosen Solution

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… Basically, 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. 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… 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. Symptoms: Built-in speakers don’t make any sounds.No sound coming from output jack (headphones or external speakers).I see the volume no-access icon (circle with diagonal line through it) when trying to change volumechecked System Preferences->Sound settings: nothing showing up under the Output or Input tabs (no “Internal Speakers” showing up)NO RED LIGHT coming from headphone jack… so it’s not the optical speaker switch problem most people seem to have.In “system information”, when I look in sound hardware… no description for input, output, etc… 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: I’ve tried all of the following in the listed order but nothing’s changed: repeatedly plugging & unplugging different types audio equipment to the headphones port (including apple headphones)disk utility and run disk repair (no errors)tried PRAM/NVRAM resets (I don’t hear the “chime” sound)tried logging in via a new user accounttried deleting ~/Library/Preferences:com.apple.systemsound.plistplastic toothpick in the hole looking in the hole with microscope & 1.8mm led to illuminate - can’t see anything obstructions in the holeI downloaded and booted the ASD software EFI and OS diagnostics - no errorstried disconnecting battery then rebootingan isopropyl alcohol swabbed q-tip cotton swab I also went to see a Genius at the Apple Store - they did their tests and said “there’s only two options: replace the logic board as we don’t replace individual components, oruse a USB adapter” The logic board repair quote was extremely expensive as my warranty is over and the charge probably includes replacing all 16Gb of memory too as it’s soldered in; and I said I didn’t think that last suggestion was very Apple-like - I’d need to carry around an ugly USB adapter and an external speaker/mic device just to hear sound! So I’m at a loss and need your help! Everything else works fine on my computer, so I’m willing to get my multimeter out and start testing hardware but I’m not sure where to start (I/O card / Logic board?). My logic board # is 820-3476-A Thanks

Sent it in for repair but, after a few hours work, they still couldn’t find which component was faulty. Ended up getting the logicboard replaced

SMC reset worked fine for me!

Sounds like power has been sent through the port by the amp, damaging the audio circuit. Check around the bottom right area of the logic board, to see if anything looks burnt. Beyond this, it would need logic board diagnostics and repair, so I would highly suggest sending it to a company who does this, otherwise you will most likely waste time and money on the tools required.

Sounds like you might have damaged the headphone connector. The mac detects if a plug is in the jack and disables the internal speakers if it thinks one is in there. I had a system where the tip of the headphone jack broke off in the connector. It took a bit of work to get the tip out.

I had similar problem with my MBP A1211. While reconnecting speakers to I/O board didn’t helped I tried reconnecting I/O board to logic board. Sound is back.

MacBook Pro sin audio Ayuda … He venido a este foro tratando de ver si alguien ha tenido este detalle, resulta que tengo una retina MacBook Pro que no tiene audio En primera instancia, pensé que eran los altavoces, sin embargo, en la configuración de sonido, reconoce los altavoces internos, incluso si conecto un auricular, lo reconoce, pero no suena Instalé BootCamp para probar con este sistema y hacer lo mismo, lo extraño es que a veces el Spearker hace un sonido, pero cuando se reinicia de nuevo es silencioso, ¿alguien podría ayudarme con lo que podría ser? Bluetooth funciona sin problemas. ¿Alguna idea? MacBook Pro with no audio. Help … I have come to this forum trying to see if anyone has had this detail, it turns out I have a Retina MacBook which has no audio In the first instance I thought about the speakers, however, in the hardware I recognize the internal speakers even if I connect a headset, it recognizes it but it does not sound Installed BootCamp to test with this system and do the same thing the odd thing is that sometimes the equipment does sound but when wintering again it is silent, could someone help me what it could be? Bluetooth works without problems. Any ideas?

I have this exact issue with a MBP13 Late 2013. I won’t open a new topic because it’s very similar. I have a MBP13 Late 2013 that worked flawlessly until recently when sound stopped working. Events are as follows: MBP13 was running macOS Mojave and updated to Catalina some weeks/months ago. I didn’t notice any issues, but some days/weeks after the update, while watching YouTube, the MBP suffered a kernel panic related to coreaudiod. I restarted and I got no audio after that. I got the “no sound” icon when trying to change volume.I did a search and found the following command to restart coreaudiod: sudo kill ps -ax | grep ‘coreaudiod’ | grep ‘sbin’ |awk ‘{print $1}’ to restart coreaudiod. It worked, but for a short period, after a day or two the audio stopped working again and I got the same “no sound” icon. I tried the command again, but now it didn’t work, not only that, inside system preferences > sound > output/input there was no devices listed (internal speaker and mic should be there).Did NVRAM reset multiple times, didn’t workDid SMC reset multiple times, didn’t workInstalled clean macOS Mojave, didn’t workUpdated to macOS Catalina, didn’t workTried plugging in P2 headphones, didn’t workOnly bluetooth headphones worksOpened the MBP13 and disconnected and connected the left and right speaker, didn’t work I’m afraid this is a hardware failure, I don’t know if it’s a logic board issue or speakers issue. If it were only the speakers, the internal mic should still work, right? But, that’s not the case as the mic doesn’t work either. What do you guys think?

Hey guys, I tried a lot of fixes and was quite sure I needed to temper with the logic board until I found this guy’s video: https://www.youtube.com/watch?v=qTbDgTWh… Hope it helps.

I had a similar problem on my MacBook Air (13-inch, Early 2015) - no audio would play, except I could change the Built-in Output’s volume. I tried a variety of fixes (resetting SMC, upgrading to Big Sur, shutting down and restarting), but none of them worked. Then I pressed Shift + Ctrl + Option + Power (usually the keybinding for an SMC reset) while my computer was still on - it suddenly shut down. I pressed power again, and when it turned on the speakers were working again. Hope this helps anyone with a similar problem!

Sooooo I have a 2015 Macbook Air that had the missing speaker problems…tried all the resets with no luck and everything else. I unplugged the power and the external monitor adapter and did an apple diagnostic boot (hit power button then hold down letter “D”) It went through the diagnostics and came back with a battery problem (its aftermarket and brand new and works great) but when I restarted from the diagnostic screen low and behold the sounds chimed…just passing on what worked for me

Not a fix but a situation that needs an explanation. Mid 2010 MacBook running High Sierra lost Internal Speakers like a year ago. Only choices are headphones or Digital Output. Read every forum, tried every recommendation but nothing worked to restore them. I’ve been using headphones and/or Bluetooth speakers since. Then one day I set up a dual boot system with Linux Ubuntu for the heck of it. When booted into Ubuntu the speakers started working. Boot into MacOS speakers stop working. I erased the entire disk and installed a fresh copy of High Sierra. Speakers won’t work. Hopefully someone can take this info and help with a solution for all. Apple threw up their hands when I reported this.
