Built-In Speakers Sound Output Missing.

I currently have no sound from my macbook pro's built in speakers. When I try pressing the volume buttons on the keyboard, a small "blocked" sign comes up (like on no smoking signs, the circle with a cross through it). When in sound preferences, under Output, there is only "Digital Out", where there should be Built-In Speakers. When i put in headphones, sound comes through as usual, it is merely the speakers themselves which will not work.

please please help!

macbook pro 17", Mac OS X (10.6.5)

After revisiting this for about the 5th time and trying the many different methods in this thread, the only way I've been able to restore my Internal Speakers was to plug in a 3.5mm headphone jack and leave it plugged in.

This causes the OS to register "Headphones" as the connected output device in Sound (System Preferences). From here, you can then set the "Use audio port for" setting to "Sound Input." This causes the audio port to switch to input mode which in turn brings back the Internal Speakers as the default Output device.

Essentially what you're left with is a dual-purpose stereo jack for your audio port: fix for your Internal Speakers and removable dust cover.

I had to insert my headphones and remove them several times before the internal speakers came back. But it worked. Using the Audio MIDI set up didn't do a thing!

Thank you very much, your tip helps me.

I resolved this issue by removing the I/O board completely. Put it back in, re-seated all connections, sound is back!

I had the same prob, poked around with a q-tip ( seemed less harmful than a toothpick) and so cool! it worked 😉

Does take more than 1-2 pokes though.

thanks guys!
