Hi,

We run a scheduled build every 2 weeks, but this time there are multiple audio related problems while no changes were made to either unity or fmod.

FMOD still runs perfectly well and the same in the editor version, but in the WebGL build things are now broken (which used to work)

Changing the volume levels of the BUSes is no longer functional  
Menu music no longer plays (other music work after another scene load)  
Stutter and broken audio when switching tabs and returning to the game tab

Again, all of these issues do not occur in the editor and they used to work in the WebGL build. I’m wondering if something changed and we need to update the fmod version? Anyone had any similar problems recently?

Thanks in advance,  
Hochey

Hi,

Are you logging any errors that we can take a look at?
