Macbook pro 13 - Sound comes from speakers instead of headphones

Question

Recently there appeared an issue when I plug my headphones into 3.5 output, the sound does not come from headphones instead it comes from the internal speakers.

The strangest thing is that Mac recognizes headphones when I plug them and changes the output in the settings automatically as it should, from speakers to headphones. But still for some reason sound comes from speakers.

I have also tried manually changing outputs, it seems to have no effect.

Mac OS 10.15.2

Answer 1

The problem was fixed by itself. Mac froze for some reason, I forced it to reboot, the problem was fixed.

Answer 2

You have the exact opposite symptom, but exact same problem as described in the question Force sound's output on speakers.

Basically, the audio jack is broken. There’s a physical switch that’s stuck in “speaker mode” and it cannot be switched via software.

You can get around this by using a USB or Bluetooth microphone/headset or use a USB DAC or USB Mixer if using a “pro grade” mic.
