OS X Mavericks is experiencing a bug where audio goes dead system-wide. For many it seems to occur when trying to play a Flash (like YouTube) video in Chrome. For others, it just seems to occur. So far, it seems limited to new, Haswell-based 2013 MacBook Airs and MacBook Pros. So what's happening and what can you do about it?
Core Audio has always been quirky - anyone who's ever plugged in headphones only to get assaulted by the delayed fire of every mail sound in the history of mail sounds knows this - but with Mavericks the bugginess is much more specific, and annoying. When it happens, all sound is just gone. It doesn't matter if you mute or un-mute, lower or increase volume, change sources, it's just gone. Rebooting fixes it... until it happens again. There are a couple of other, quicker fixes you can try instead.
- Plug in and then take out headphones.
- Kill the Core Audio process in the Activity monitor.
- Reboot.
Hopefully Apple pushes out an update to fix this, and soon. In the meantime, are you experiencing the problem, and if so, any fixes working for you?
