No sound (startup chime works) but nothing else
Long story short, I had switched out a hard drive on an older computer with the same system after a nice big computer fail and when I started up the "new" computer, there was no audio. The start up chime is still playing but my computer does not pick up input and output audio components.
No red light, headphones don't work and the pop up icon when you change the volume shows it full with a little CROSSED OUT CIRCLE.
Getting impatient. Tried resetting SMC, PRAM, headphone jack wiggling, nothing works. Anyone got any idea WTF is going on.
