Q: I can get no sound of my MacBook Pro, after I unplugged some speakers. The 'internal speakers' doesn't show up on output devices.

Please can someone help me!

I took out some speakers from the headphone jack, and the sound stopped working. I have tried putting the speakers back in, putting headphones in, but nothing works.

Is there something I could do with the MIDI set up? I really dont know.

Mac Pro

    Highlight  Internal Speakers / Headphones

    Make sure that Mute is not enabled.

 

2.Plug in and  remove the headphone.

 

    If you see red light in the headphone port or not, plug the headphone

    in and out of the port 5 or 6 times to flip the microswitch inside.
