The sound on my powerbook went out suddenly and i have no clue why. I have gone into my system preferences/sound tab and have all the settings to where they should be, however i noticed that in the output tab there is only the option for headphones. I have no clue if this is normal but I feel i should be seeing the option for internal speakers in there as well. Could that have fallen out? Does anybody know how I can make that an option again? I appreciate any help anyone can give me. Thanks!
