AirPlay Mirroring

I am unable to stream sound in airplay mirroring. I have tried to change my sound system preferences but that doesn't work.

OS X Mountain Lion, AirPlay

This is happening to me as well but I found a solution. Things I have noticed:


1. Apple TV can't be selected (switches back to internal speakers)

2. Airplay Display Mirroring continues to work

3. Airplay from ITunes still works

4. Seems to happen after the computer sleeps.


SOLUTION!

In the terminal, enter:

sudo dscacheutil -flushcache

sudo killall -HUP mDNSResponder


This isn't ideal, but it works. Flushing out the cache seems to remove whatever is causing the issue.

This bug still occurs even with the latest updates installed of Mountain Lion. It is definitely a bug on Apple's part, a sign of a true lack of QA testing. I have spoken to AppleCare agents and they confirmed there is nothing wrong with what I am doing. Hopefully Apple will prioritize a fix for this in the next release cycle. AirPlay Mirroring is one of the major uses I have for my laptop now and I find this endlessly frustrating as I have to reboot almost daily to fix this problem.

I just experienced this for the first time on my 2011 Mac Air. It has worked great up till now.

Weird. I tried the dns cache flush but it did not work.

Will try reboot.


--- update

I rebooted Mac and Apple TV and streamed sound came back. Thanks for the tip!

This did happen right after an OSX update. It did not prompt to reboot but I guess it was necessary.

I have the same persestint issue that comes and goes without a restart. I also have a problem that only my main account on the computer-macbook pro 2011- will air play the display all other accounts have a scrambled screen displaying random info not associated with that account. looking foward to a update that will correct this.😐
