I plugged in a stereo through analogue mini jack to the headphone socket of my mac book pro. When i unplugged the stereo, the internal speakers failed to work. There is now a red light coming from the jack as if a "digital output" is plugged into the socket. But no digital output has ever been plugged into the socket - and I have no control of mute or volume settings.

When I plug headphones in, they work fine and I have control of mute and volume settings. Once the headphones are removed I am automatically set back to "digital output" with no control over mute or volume, and no audio from m internal speakers.

I have tried changing the settings in system preferences/sound/settings/output ... but there is no option other than "digital output". I suppose I would like to select "internal speakers" but there is no option for this. And like I stated earlier, the jack is lit up red.

I've tried software updates, restarts, disk utilities (permissions and repairs including repairing with the startup disk), plugging and unplugging, but to no avail.

When I try to change the volume on the keyboard's volume controls I get the "no entry" sign under the volume bar and have no control (as if it were stuck on mute).

The only thing I can think of is that I forced a mini jack into the headphone socket too hard so I'm worried that I've damaged the hardware.

Could this have caused the problem? Or is this a software issue? Any help would be appreciated.

In short I have no sound from the internal speakers.

    After writing a lengthy message I searched the boards and found the fix... simply take the headphones and place them in and out the socket until the light goes off. This worked for me.

    Try using a toothpick in the headphone jack to reach the digital switch.

    Same here. I don't remember doing anything out of the ordinary. I was working in Parallels on getting a AM station to stream via some web interface. Next time I went to play sound on the internal speakers, no go.

    I've tried zapping the PRAM, toggling the headphone jack and the toothpick thing. Nothing seems to work.

    I've also noticed that I get sound in my headphones in iTunes but not in Garageband (someone had suggested that starting up Garageband would reset things.

    Any other ideas out there?

    Is there a file that could get corrupted that I could switch out of my back up?

    Run Audio MIDI Setup (Utilities Folder), set "Properties for" to the output device, and make sure it is set to 44,100 Hz, 16-bit, with the volume sliders to the right.

    I tried running Audio MIDI setup to no avail; the only source for the built-in output device is "Digital Out" without my headphones in. I can't get "Internal Speakers", and I definitely can't change the settings.

    I'm considering reinstalling my OS. I've made a complete backup of my system to transfer over via Migration Assistant. Will this issue be corrected for sure if I do this? Or could the problem exist in the settings that get transfered back from Migration Assistant?

    Anyone know?

    I had this problem too, black MacBook. Plugged a pair of headphones in and out a few times slowly and it fixed it.
    Not sure if the problem will stay away.

    I guess there is something wrong with the Black MacBooks. My internal speakers come back but only after running my external drive (which hums the desk I'm on just enough to jiggle the sensor back in place). I can't get them back with the headphones trick.

    I guess I'm gonna have to get this fixed by Apple, what a pain!

    I have a newer Mac Book with tiger and can't get any sound out of it at all. I don't hear the starting noise when it turns on and it won't recognise any sort of audio drive. I have the red light on in my headphone jack and can't turn it off with the toothpick deal or anything. Help, somebody?

    Thanks to you all...I tried a paper clip and then the headphone jack 20 30 times - then I started to tap on the top above the jack.....then I was banging on top and jabbing the jack in and out - kinda felt sexual!..then voila.....the Clash started playing - "One More Time"....if the title of this song is any indication I better get this little sweetheart to Apple for a checkup...

    fwiw, I have a MBP 1.83 and had the same problem, only it started when I had my MBP on the floor, plugged into my speakers so that I could listen to music in the shower.


    anyway, my place is a mess, and the mbp stayed on the floor for the next hour or so, and when i finally came to my senses, I snatched it up (forgetting that it was connected to the speakers) and the mini plug yanked out.

    All this is to say that it probably is related to some sort of mini-jack trauma.

    But the in-and-out trick worked for me.

    Good luck!

    I too was able to push and pull the headphones out of the jack and get the internal speakers to work. The Process: Played song in iTunes; Left hand: Pushed and pulled headphones out of jack; Right Hand: ajusted the volume up and down as I pushed and pulled the headphones.

    It worked for me. I called apple and they told me to reset the PRAM. That didn't help. At all. Thanks Apple.
