Okay, I only just noticed this while I was Skyping. I let my D820 go to sleep, and woke it back up. But then, when I go into another Skype call, the other person cannot hear me. I go into System Preferences, and into Sound, and the test meter picks up nothing. I can only fix it by plugging in a pair of headphones into the microphone slot, and unplugging it.
I know it's a simple solution, but I just don't like to carry a pair of headphones to fix my Mic. I use the Mic alot of times on the go, and I sleep my computer alot of times. Anyone know how to fix this issue permanently?
