internal speakers won't turn on
MacBook Pro 17 A1261
I use an amplifier to listen to iTunes, but recently I discovered that my internal speakers were off, being grey on the finder. Opened System preferences to see that internal speakers were no more identified there instead were Soundflower 2ch and 16 ch. So I uninstalled Soundflower but that did not solved my problem. Also I noticed that bringing my headphone jack closer to the unit gave me a red light coming out of the output jack.
After researching on Apple forum, someone suggested that MacBookPro's had internal switch for headphones and the switch was stucked turned off. One way to turn it back on was to use a toothpick and try to touch it and turn it back on. That worked allright except that every now and then the problem comes back again. Now to my question. Does anyone know how to replace that switch ? Is it difficult ?
