I do not have a video tutorial unfortunately. Importing 3D models from 3DS Max into FLARToolkit can be tricky especially if you are trying to also bring in any animations. Adding music should be easy and no different than loading music into any other Actionscript project. I’d suggest doing google searches to find forum posts and code snippets which could point you in the right direction. I have seen code out there that shows how to load Collada 3D models from Google Sketchup into Papervision 3D flash projects. FLARToolkit uses Papervision to render the 3D scene.

I am impressed with your developments.
I’m new to the subject and let me know if you have video tutorial is for sharing.

Just let me know if you help me with the source code for an animation 3dsmax cluck in FLARToolKit adding music.

Thank you for your contributions.
