No sound with mirroring

had no sound on appleTV whilst using VLC imac mountain lion airplay mirroring

sound was still playing on imac

came here read a few comments didnt try anything

tried to play video again and it started working for no reason

im just as baffled as everyone else

never had a problem with quicktime player mirrored to appletv but that junk wont play avi files for me

so is the problem: appletv or mountain lion or VLC or imac ?

Thank you DC Soup. This fixed it on my mid-2009 MacBook Pro.

did not work for me :/

UPDATED TO NEWEST APPLE TV VERSION 5.1: -----------> everything working great!

I can now connect to speakers by option+clicking the speaker symbol in the top bar
I can now connect itunes to speakers by clicking the airplay symbol in itunes
When I mirror my display now, sound always plays back too!

EDIT: This may just be temporarily buggy but I will post anyways incase somebody has the same issues:
1) My photostream screensaver will not play anymore. When I try to log in to photostream (over the photostream icon on homescreen) it displays "unable to sign in - Apple TV cannot connect to server at this time".
2) I noticed that when I airplay music over iTunes to appleTV (music I did not buy on the itunes store), the appleTV just displays "unknown artist- unknown track", even though the ID3 tags for the songs are correct.

sound does go through the mac to apple tv via mirroring but you will have to re-start the system. i am having the same issue. everytime the apple tv goes to sleep, and comes back on the audio will not go through but after a restart it works. kinda annoying.

i also have same problem with the video, it says the device is not on or connected to use mirroring option but it plays airplay though. we need an update on this apple

Stream video and audio using VLC (v2.03) and AirPlay mirroring. OS: Mountain Lion.

VLC - Audio - Audio Device - switch from 'Built in Output' to AirPlay.

Resulted for me in streaming audio.

Confirmed this works.

You have to take your apple TV to the homescreen (out of Netflix etc) and then go into sleep mode. Wake from sleep mode and go back to homepage and then your audio will work.

Have exact same issue.

What I did was - restart atv. I tried to change sound source in VLC and it helped! Thanks stijnbl!

But still problem is not solved permanently and it is really annoying.

If it is just vlc then try to quit it and restart vlc again. It helps for me. But some times it doesn't stream any audio at all to the atv until I restart my mbp. It's really annoying. Control+volume and Apple TV also doesn't work for me because as soon I click on atv it takes it back to the internal speaker selection. Didn't expect this sort of bug from apple at least. After the arc update things are going pretty smooth but it still does it some times which makes me mad as ****. I think the HDMI is still the best option as atv doesn't even support extended desktop. ATV ***** Apple

Thanks. This worked for me. Although I find it ridiculous that a company that boasts 'it just works' requires you to implement this work around to make basic Airplay functionality work.

Wahoo! This fix totally worked for me, stijnbl. Thanks!!!

I have the same problem but with my new iPod Touch 5. The videos I take with the touch have no sound when mirrored.

This helped me. thx

I changed my audio setting on the Apple TV settings to 16 bit and that took care of the no audio issue.

This worked for me thank you!!
