This has not been a good past couple of days! My iPhone 4 speakers "went out" due to what I believe was using to much alcohol for cleaning the home button...the water damage indicator now looks pink...and the phone thinks it is always connected to the dock connector. Well to make matters worse...my MacBook Air speakers are not working...no sound is coming out of them...but they did work when I first turned it on this morning for the Apple boot up and I heard the Apple chime, but after that nothing...no sound! No sound for videos on YouTube...music...iTunes...but in iTunes the music has to be played through my airport express speakers to hear music. No...I did not also clean my MacBook with anything! Am I missing something...is there a way to test for sure if it is my speakers failing or not?...software issue? Mute somehow on?
