I have a sound problem in where it doesn't output sound
MacBook Pro 13" 2009 A1278
I have a sound problem in where it doesn't output sound, the sound displays crossed out. The original problem was the speakers had a crackle sound , I then replaced the speakers L/R. When I restart the the MBP, I do hear the Apple chime once but the sound appears to remain disabled.
Anything that i should be looking for?

Dan, thank you for your prompt response. Regarding the headphone jacks, I barely use them but none the less I have checked them and they seem to be in order. Somehow I still have the same problem in where the sound symbol appears when I press sound up/down but below it also displays “ø”. Note that the Apple chime sounds when I restart the computer. Your help is appreciated.

@gonziva - Yes, the chime sound can confuse people as that tells them the speaker is working!
But! That connection is not via the headphone jack left and right lines but via the Subwoofer speaker to get that nice deep base sound.
Then the jack connection on the logic board has an issue. I would use an meter to see if the jack is bad at this point.
This is a tough repair to replace the jack unit as its easier to replace the full logic board thats what I would do at this point.
