3.2. Airplay or sound not working?
Here are a few things to try if you are having AirPlay issues:
- My projector is a blue screen, but I AirPlayed on my computer:
- This means you are on the wrong switcher channel and must change it to the Apple TV one (small black box).
- If that still doesn't work, press the "Source Search" button.
- I can't see the AirPlay icon on my computer's menu bar:
- Are you on the JPS Bonjour WiFi network?
- Are you using a Chromebook? These cannot AirPlay and must be hardwired in for screen sharing.
- I see the AirPlay icon, but can't find my room number on the list:
- Go into your Apple TV settings> General>AirPlay>Turn off>Turn on. Then wait a few seconds and check the list again.
- Unplug The Apple TV, then plug it back in after a few seconds.
- I click on my room number, but nothing happens:
- Restart your computer.
- Unplug The Apple TV, then plug it back in after a few seconds.
- I can't get sound to play during AirPlay:
- Is your Lightspeed audio unit on? (the button should have a blue light).
- Is the volume knob on the Lightspeed unit turned up?
- Is the volume turned up on your computer?
- Are your audio output settings set to the Apple TV? (On your computer: click Apple logo in top left, system preferences, sound, output, then select your Apple TV#)
- Sound system is Echoing
- The projector's speaker is probably on. Turn this volume all the way down with the projector remote (speaker icon near the bottom).
- The projector's speaker is probably on. Turn this volume all the way down with the projector remote (speaker icon near the bottom).
- I can't get my portable DVD player to AirPlay:
- Apple does not allow AirPlaying of DVDs, so it blocks it. You must hardwire in to screen share DVDs.
- I've tried all of these, but still can't AirPlay
- Submit a support ticket and we'll come assist you asap.
- Most rooms have an option for hardwiring in to share you screen
-
How to Hardwire in:
- Find your HDMI cord with the short white/tan DisplayPort adapter (sometimes inside a textured black cord). Plug this into your computer, then change your switcher to the computer channel. You may have to hit "source search" on your projector.
- If you have a TV: plug the other end of the HDMI cable into the TV and switch the TV input to HDMI. (Kids First building: unplug the orange HDMI cable already in the TV, then plug yours in)
