I am trying to set up an iPad for the classroom and have a quick question about audio and video from the iPad.

 

I would like to use Airplay to send Video to an Apple TV connected to a ceiling mounted projector. I am unsure about how to deal with audio though. The options are to attach speakers to the AppleTV, bt withthe way it's mounted this may be a problem. I would prefer to send the audio to a set of bluetooth or AirPlay speakers, either from the iPad or from the AppleTV. In this particular instillation we will probably present from a single location, so even using a pair of plugin speakers would be OK, I just don't know if I am able to keep audio and video separate.

 

Thanks for any help or tips you can offer.

    Apple TV can send its audio output to another AirPlay device (e.g. AirPlay speakers, an AirPort Express, even another Apple TV).  So the Apple TV's video output would go to the overhead projector via HDMI, with the audio would be sent out to a remote audio device via AirPlay.  All this with the source of the video originating from the iPad.

    I actually investigated what you're asking, and what happens is that the you'll get a lag on the sound, so the audio and video would be out of sync. And I was trying this from my iMac which gives me much more powerful control over how to output sound.

     

    With your iPad, you don't have that kind of choice. You can only choose one output, which would, in this case, be Airplay. You could use the AppleTV's optical out or use its Airplay sound out and try to sync the sound, unless there's no lag.

     

    You can't even run sound out of the headphone jack to external speakers while Airplay is running.

     

    You're kind of stuck.

    Actually as of the 5.2 software update, Apple TV does support sending audio separately to an Airplay device and having it work in sync with the video:

    However, it seems still limited to certain apps (such as Youtube on iPad) and general AirPlay mirroring doesn't seem to offer this option.  Someone please correct me if there's in fact a way to do this when mirroring...

    Re-routing the audio to a different AirPlay device is done from the ATV settings, not from the AirPlay setting on the iPad (or whatever you're using as the AirPlay source to play through the ATV).  In ATV settings, you can designate a different AirPlay device for audio output.

     

    I know this works with videos that are resident on my iPad, and when playing content that is selected by the ATV (rented movies, YouTube, etc.)  What I don't know is if it works for 3rd party apps that mirror from the iPad to the ATV -- i.e. can the audio portion of mirroring be re-routed to a different AirPlay device?  That I don't know, but will give it a shot in the coming days.
