Recently my macbook pro (2010) speaker sound stopped working and I am cannot adjust the volume. When I plug in headphones the sound works and I'm able to adjust the volume etc etc. However, when I unplug the headphones the headphone jack has a red light coming out. I tried googling the issue and the solution was said try resetting the PVRAM or something (CMD+OPTION+P+R when rebooting). I get the "DOOOOOOOM" sound when first booting up a Mac. But after logging in the speakers does not work at all. I went to Apple the other day and they said its an issue with the logicboard and would cost $280 to send my macbook to their repair shop to get it fixed. When I got home, there was an update for iTunes. I updated my iTunes and somehow my speakers were working, but after a few hours, just the speakers/volume went out again... So I guess, my question is, is it replacing my logicboard the only option I have to fixing this issue? Thanks!
