    Hello all,

    Im building an AR app that uses 6 different target images to trigger 6 different videos - it's for an arts project. It all seems to work well apart from the audio. When I set the audio to Play on Awake all 6 videos start up - if I take it off the video stops running, I get a grey floating square. Also the audio continues to play even when I lose the target. I need the video and audio to stop when target image is dropped so that users can scan different images. I have made the app without using code - I am hoping for an easy fix as I don't code..... hoping for a check box solution?

    Really appreciate any help

    Hi,
    I have figured mine out, but it does require a little bit of copying and pasting code.
    I am on OSX
    Unity 2018.3.9f1
    Vuforia 8.1.7
    Xcode 10.1

    I have an ARCamera, an ImageTarget with a Quad Child and my video with embedded audio attached to a video component within that Quad.
    If PLAY ON AWAKE was checked, the audio could be be heard as soon as the app fired up and before the image was tracked, the video had also started, although I couldnt see it until it tracked the image then it would start from whereever it was in that video, so was in sync with the audio.
    If tracking was lost the audio carried on, and the video would also have carried on, although not visible, and then would be visable once tracking started again, but would be further along the video an be in sync with audio.

    If PLAY ON AWAKE was unchecked, the quad would just remain grey when tracking was found, no audio or video would play.

    I added a bit of code to the defaultTrackableEventhandler script in the ImageTarget inspector.
    It does not reference any specific file names, so if you replace your script with the one attached it should work?
    I would do a backup version of your original project first just in case, I am new to this!

    Hope this helps.

    Hi, I am having the same issue, I tried the script and it's not working as expected. I still just get a blank quad displayed once the target is detected.

    Any ideas?

    Thanks
