    I'm working on my MacBook air today and all of a sudden the sound drops out completely.
    Internal speaker and headphones.

    What's going on?
    Is my trusty MBA finally showing signs of aging?

    I tried to reboot it, worked for a little while, like 15 min, and then sound is gone again.
    Also looked to see if I had the latest OS and yes, I do.
    I have nothing in Sound properties other than "Internal Speakers".

    Any ideas?

    Try an SMC reset - search for instructions on the Apple site

    It won't hurt to do it. I use it sometimes on a Retina Macbook when USB accessories stop working. It is a hardware function and does not affect user or network logins, preferences etc.
