Why does my MacBook have no sound?

Hello

I have a Macbook Air 2019 Model A1932, and the speakers just doesn't wan't to work.

I've tried alot of things to get it back working, yet it's still not working.

  • Reinstalling macOS
  • Updated macOS
  • Restart CoreAudioD
  • Replug Speakers
  • Ran Apple Diagnostics, No Errors
  • Tried Safe Mode
  • Resetting NVRAM & SMC

In my top bar, there's no sound icon. When i go into settings, and click sound, then the Macbook does recognize the speakers. But still won't play any sound through them.

Bad speakers maybe?

And it has no water damage, for anyone wondering.

Update (03/18/25)

Audio board is cooked @livfe

And so is the flex cable

Now it’s confirmed

@danj Figured, still don't know how

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@hiyxus - doesn’t always due to a spill, it could be humidity (condensation from taking the system from a cooler AC space to a very humid outside).

Nice to know now, was so confused. Well time to find a new audio board and flex cable

A common issue with headphone jacks is the switches held inside, here’s a deeper dive into the different setups Understanding Audio Jack Switches and Schematics, jump down to Switching Audio Between Speakers and Headphones.

The easiest fix here is just replacing the MacBook Air 13" (Late 2018-Mid 2019) Audio Daughterboard as outlined in this guide MacBook Air 13" Retina Display 2019 Audio Board Replacement

Have you tried using a bluetooth headset and a headphone via the jack port?

A post here might shed some light (Audio board issue)?

Yes, i've tried using a bluetooth headset and then it seems to work, also a bluetooth speaker, also workd.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

Let me rephrase that

Yes, with a bluetooth headset connected, then i get sound in my headset. When using a bluetooth speaker i get sound in the speaker. But when disconnected then the internal speakers still doesn't wanna work

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@hiyxus Same symptoms as in the post I linked to before, check it out, seems likely the Audio Board has develop an issue sadly.....

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

So what you're saying is that it might be my Audio board that is cooked? Even though there is no water damage, and touch id works?

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@hiyxus Cannot be 100% certain, but if your able to follow the steps to diagnose it from that post it may confirm it. These things amongst others can 'go wrong' by themselves unfortunately.
