Headphone/External Speaker Jack stopped working
I had powered Altec Lansing speakers hooked up to my 24" iMac and they worked fine for ~1 year. I recently upgraded my RAM with no difficulty, however afterwards, the headphone jack no longer recognized the presence of the external speakers. The sound preferences panel "output" tab shows "Internal Speakers" and "Built-in Output" regardless of whether the external speakers are plugged in or not. Rarely and for a moment, if I plug and unplug the speakers from the headphone jack, the sound panel occasionally shows "Digital Out" but still no sound and it quickly reverts back to "Internal Speakers." Any thoughts?
Es esta una buena pregunta?
I have tried everything mentioned here and nothing works. I have used speakers connected through the headphone jack for years until today. No audio/headphone out shown, only internal speakers. This with the speakers connected and they differently work fine.
I am using a iMac 21.5 mid 2011.

I used my 2008 iMac for 14 years with altec external speakers, and then one day out of the blue the jack stopped working. It wouldn't work with headphones either. That was the straw that broke the computer. Now I've got a new iMac and frankly I'm afraid to plug in the external speakers! Perhaps I'll try to purchase some apple branded ones?
