NO SOUND output (except for start-up chime) on MacBook Pro
I've been looking all over the discussion boards but haven't been able to figure this one out.
Suddenly for no apparent reason I have no sound output. I've checked all the settings, repaired disk permissions, restarted, etc. with no effect. I DO get the start-up chime but then nothing. Also, I do NOT have a red light emitting from my adio out jack. F3, F4 and F5 show the volume icon changing on-screen but with no actual sound output. Switching to a speakers or earphones doesn't change it either.
The only thing I can think of is that my battery has been slowly dying and has just recently started to crap out when the battery life indicator shows more than 50% charge. For this reason the computer has lost power and suddenly shut down once or twice without having been properly shut down. But the loss of sound input did NOT happen directly after this.
Any suggestions?
