Guys, Its a strange issue that my air is currently going through. On most of the occasions when i wake it up from sleep, there's no sound, i checked Audio MIDI settings, and general sound settings, everything is fine there, nothing is on mute. The sound buttons do show the bars going up and down but there's NO SOUND at all. Solutions already done: 1. I have done PRAM reset, SMC reset 2. I have restarted Yes, both #1 and #2 have worked, but i DON'T and SHOULD NOT be doing this every time to bring the sound back. Note: I had Headsets Plugged in earlier on 1 occasion and after that i had the same NO sound issue even with no headsets. I am running OSX 10.9 Please advice....!
