I unplugged my headphones 2 days ago and a red light coming through the audio out hasn't turned off since. there seems to be no audio driver for the internal speakers and core audio. When plugged with headphones or speakers again it works.

Check if there is any sound coming out of the headphone (using headphone and playing itunes). If there is none. Goto System Preference > Hardware > Sound > Output ; check if the output is assign to internal speaker and it is not muted. Do a visual check at the headphone connector, look into it, see if you see a red light emit from the headphone jack (indicate that the fault is in the headphone connector, it's trying to output optical spdif).
You laptop may have sound prefs set to external speakers, or
if there is a red light coming from the headphone jack. the mac thinks the headphones are still there.
Plug in and unplug the headphones an see if the red light goes out. may take a couple of times. Be gentle
Your headphone jack is either contaminated or broken. Clean any debris you see inside, if that doesn't help, it may need replacement. If you want somebody else to do it for you go to Macbook Repair. If you want to do it yourself, here is an Macbook Repair Guide that shows how to repair a Macbook.
This is a known problem with the combo Analog + Digital (optical) audio jack on all modern macbooks. There is a microswitch inside the jack that detected the presence of a optical toslink connector and will disable the analog audio hardware if the switch is toggled. Due to a design flaw in the jack, sometimes simply plugging in regular headphones can cause this microswitch to toggle. While this is annoying, you can work around it if your mac is no longer under warranty.
There have been many internet group discussions about this issue and many have recommended inserting all sorts of small, thin devices in the jack to poke around and un-toggle that little switch. I personally find that too unsettling and will likely cause more damage than good. I have found that simply inserting and removing regular headphone jacks several times in quick succession will clear the fault. You can also try inserting the headphone jack and trying to wiggle it a little while in the jack. Be careful, the audio jack is surface-mount soldered to the motherboard. If you pull too hard, you can dislodge it from the logicboard and you WILL be making a trip to the apple store.
Next time you encounter this problem, turn your macbook such that you can look directly into the headphone port and look for a red glowing light. If you see that light, the port is in optical mode and that is why your speakers don't work.
With regard to the sound controller working... I disagree with the previous poster. These days the sound controller is integrated directly into the motherboard chipset and it is unlikely for that part to fail and not affect other capabilities. In the older days of Old World PowerPC macs, the audio engine was a separate set of chips, and controller failure was possible. Not so much these days.
Have a look down the jack socket where you would plug in speakers or headphones - is there a bright red light?
If there is it means that audio is being routed through the digital output not the analogue (which includes the internal speakers)
Go to system prefs and check on Sound - last icon in the second row.
There should be at least three output options listed, digital, line out and internal speakers. check Internal speakers and that should be it.
However. Just lately I have seen 2 white macbooks that have only DIgital listed and have been unable to fix it.
why use windows7? you paid for your macosx that comes with your macbook and mind you that macosx is a very powerful operating system and way better than windows. i suggest you use the macosx. you'd be amazed on how easy it is to use. i myself am a mac user and i assure you you'll never have to worry with viruses again.
anyway, if you insist to use the windows7 i think the problem there is the driver for your audio. you might need the bootcamp driver on the cd that came with your macbook. try installing the audio driver and i am almost certain this will work. the red light shining in it is the laser used with fiber optic cables. your macbook is equipped with an optical audio port if you wanted a digital output going to your sound system (if it supports optical inputs).
Later MacBook (Pro) use a mini-DVI connector that does not pass analog needed for composite or S-video. Was yours ever working? And most DVI connectors do not pass sound as seen by your cabling. You cannot detect display through RCA. You just set it in Sys Prefs :: Displays, try some other settings, although your seem right.
I have a white early-2009 MacBook and mini-DVI to HDMI adapter (monoprice <$10) and HDMI cable and have not connected the TOS-link for sound, yet--just slideshows at 1920x1080. You will get a much better picture digitally.
I took a safety pin and put it in the notch inside the headphone jack input. notch is located at 12 o'clock about 1/8th inch in, (this is an important step, other steps are no good until red light is off) the red light went off (Be patient this step may take time) still no sound, I then went to Audio MIDI setup (Should be located in Applications/Utilities), go to Audio in menu bar (at very top of computer screen) and selected 'open Aggregate Device Editor,' clicked on the + to add a device I then had a few options show up in the lower [Structure] portion I clicked on all the 'Use' boxes and the built-in output bubble selected done. I then Selected Configure Speakers in Audio MIDI setup and I can test my left and right speakers individually, they put out a fuzzy test sound, pressed done when finished. They still didn't work so I set Default out put to the Aggregate Device I created, then turned on Itunes and it was working fine I just could not control the volume from the F3, F4, & F5 buttons so I went to sound in system preferences and made sure the built-in Output option was selected. I was then able to control the volume. The red light in headphone jack input may come back on if anything is inserted inside, just mess around with the notches inside till it goes off. Hope it works as well as it did for me. Good luck and please feel free to quote me and share this solution with others.
