Macbook Pro Audio problem

Gillo

Just wondering if anyone can shed any light on this before I get in touch with Mactivate.

I have a 15" Macbook Pro, 2.2 Ghz, funning 10.5. Up to yesterday the audio was running fine, I plugged in a set of earphone to listen to some music and they worked fine. Then this evening when I go to use the speaker's there's nothing happening and the audio controls don't work either, the optical out is working (the red light is on, so I'm guessing it's working) when I plug in earphones they work perfectly but when unplugged the speakers still won't work.

Thanks, in advance.

Yup I had this exactly problem before and i had to reset some MIDI settings oddly enough, also take a needle and *wiggle* in the audio jack socket until the red light goes off. Ill post more detail later, right now im functioning on a couple of hours sleep and 10 or so hrs driving.

Start Garageband, and a new project, exit it again.
Try now.

Not if the optical jack light is on, Garageband isn't going to help that. Sometimes it does hijack the audio and mess up settings but if the light is on then its h/w related. Try the pin, seriously! I had a thread on this a few months back, Ill see if I can dig it up.

Here was the problem:

My internal speakers are GONE!!! My audio output was set to DIGITAL OUT and no other option was available.


With NO HEADPHONES plugged in this WAS the problem:
- Volume is GONE... no alerts, no audio, no startup sound NOTHING
- Volume keys on the keyboard do not respond,l I simply get a 'forbidden' logo, you know the one you get sometimes the circle with the line...
- Volume slider does not move
- The red light is also on in the audio socket (you know the jack glows red because of the laser in there to send audio digitally if you were to use an optical cable)
- it fecked.. so I do all the usual things to check what is going on, being a bloody audio head... nothing.. every APPEARS to be normal. So... Katie starts to panic.

Plugs in headphones:
- Slider works again
- All volume present and accounted for
- buttons work

Boot-up in XP
- Volume is also fine!


After much panic, and checking every audio setting on the machine.. I resorted to SERIOUS depths and decided to try and force deactivate the digital light by getting a headphone jack (unconnected) and putting it in HALFWAY into the socket and doing alot of jiggling - after about 2 mins of this, the light went off, problem solved, crisis averted.

Im going to leave this here though, in case anyone else ends up with the save problem!

Thanks, I did something similar after checking online, plugged and unplugged the earphones a few times.
