Hi,
While the warning you’re observing is expected, FMOD versions 2.02.07 and above should be handling the required resumption/creation by default. I don’t recall having the problem you’re describing when I tested your website project for a previous issue you were running into: FMod Web API Failed to get parameter
What version of FMOD are you using? Also, can you elaborate on what exactly you mean by “not stable” - is it just that you don’t hear any audio, or do you also get artifacting such as stutters?
