    Hi, I have an early 2010 MBP 13" that's been doing great ever since I got it. However, I noticed a few days ago that the internal speakers were not working anymore when I took my MBP "on the road" (I use external speakers via the earphones output at home).
    Whenever I unplug my external speakers, the volume control in the upper right corner of Mac OS goes gray. Moreover, I can't even select "internal speakers" in system preferences/sound/output: the only option available is some optical output (the earphones output I assume), and I know for a fact that there should also be an "internal speakers" option available.
    Does it seem like a hardware or software problem? I've read in some other posts that there can be a problem with the earphone output (some kind of sensor problem that makes the MBP unable to recognize that the earphones aren't plugged in, something you can fix with a sharp object, don't remember exactly), could it be it? Also, I recently installed Win XP using bootcamp (I uninstalled it since), could it be the cause?
    Thanks in advance!

    Is there a red light visible in the 3.5mm/TRS audio jack you use to connect external speakers to the MBP? (that is the optical output)
    If so, plug and unplug a 3.5mm/TRS plug (the one from the external speakers or headphones, if you have) until the red light goes away.
