I wanted to ask you to clarify if you really mean that it is impossible to mirror the screen to ATV so that the video output and audio output are distinct yet are guaranteed to remain (more or less) in sync. I have finally gotten down to test the Apple TV using some other bluetooth audio device, namely headphones. Also, if I use the tiny speakers on the projector, everything again works fine, so it's somehow only the connection between the two ATVs when screen mirroring that produces the lag.

It is also not possible unfortunately to mirror the screen to one ATV and airplay the sound to another. So the problem is just with standard screen mirroring with two ATVs.ĭoes anyone have an idea what is going on? I have restarted all devices and reset both ATV's and generally fiddled around with plenty of settings, but to no avail. Everything also works when I send the audio to bluetooth headphones. It also works if I use airplay in-app: either airplaying a movie via QuickTime on the computer or playing a YouTube video by pressing the AirPlay button on the video on my iPhone. If I airplay just the sound to either ATV, everything works fine. All sound starts late, stays lagging behind, and stops late after the mirroring ends. When AirPlay mirroring my MacBook Pro or iPhone screen to the 5th Gen ATV, I do get a good picture with the projector and the sound does play through the speakers, but always about 4-5 seconds late. ATV connected to (old, non-bluetooth) speakers. ATV via HDMI to my projector (Epson EH-TV5350) and send its sound wirelessly to my old 3rd Gen.
