WebGL & Unity & SoundLoop (Looking for help)

Hey all. After the third participation on the LudumDare we mentioned a big problem with looping the sound.

We work with Unity and want to build a WebGL-Version for the easy-play.

What we do: - play the first part (start-sound) - use PlayScheduled for the second part (loop-sound). The loop attitude from AudioSource is - for sure - true.

The loop-sound will also start after the first part, but just once.
This is just a problem after building a WebGL-Version.

Did you also notice it? Do you maybe have a solution or workaround?

Thanks and well coding!
