The 'sudo killall coreaudiod' command does work, thanks for that little tip. This points directly toward issues with the AirPlay audio device and other under-the-hood elements on OS X. It has nothing to do with the network of course. I hope they fix this in OS X 10.9 Mavericks.

Same thing here. No audio when air playing video. Early 2011 MBP, ATV2 and last gen time capsule. Killing coreaudio worked.
Is there a script that we could use to automate the process?

Thanks netsoup, killing coreaudiod worked for me.

Apparently not... I'm running Mavericks and had the problemo

I'm running Mavericks and am still experiencing this problem. Only fix is to kill coreaudiod or reboot. What a pain.

I found out that the built in firewall interferes with AirPlay (which I know is weird).
Try turning the OS X firewall off using System Settings -> Security. If AirPlay now works, turn on the firewall and add "coreaudio" to the list of exceptions. This worked for me.
By the way, Coreaudio is the OS X system driver for audio.

Wow. Thank you for the additional info.
I did not even think the OSX firewall would interfere with Airplay audio. That's never happened to me, but good to know to add that to the list of possible issue cause/effects!
Every airplay audio issue I've had, it's come down to closing what I'm doing, killing(restarting) coreaudiod, then going about my way. At first I needed to restart the computer, which was super annoying and unworthy of such a fantastic product, then I realized thanks to others posting solutions I could just exit airplay and restart coreaudiod. Since then I found out sometimes I need to actually close safari or whatever is having issues, restart coreaudiod, then resume my merry way.
I am not an OSX developer (yet), but if anyone here is, this is a perfect bug to report. It's been happening to me off and on since Snow Leopard.

I am also having this problem.
I have brand new Late 2013 MBP 15" Retina and lastest model Apple TV.
Reboot fixes the issue.
The only thing "unique" about my network is that I have 2 Apple TV's on the network, perhaps this is significant in triggering the bug.
This is a bug... Apple please fix!

I notice that the no-sound-over-airplay-when mirroring-to-appletv problem only occurs on my imac after I've used headphones. Whether the imac has been to sleep or not doesn't affect the working of sound to the AppleTV. It will work all the time, except if I've used headphones, after which, the sound won't play when mirroring to the ATV. [Rebooting makes the sound work again.] Anyone else notice whether use of headphones "causes" the problem?

We have a 13" rMBP running Mountain Lion. Streams perfectly. We have a 15" rMPB running Mavericks, streaming w/o audio.
* Firewall is off
* Rebooting/sleeping/etc doesn't help
* sudo kill coreaudiod doesn't help
* switching to 2.4MHz doesn't help
* using AirParrot instead AirPlay works perfectly!
What?? Anyway, my suggestion for people who have tried everything else is to buy AirParrot.
