5.6 webassembly 3D audio

Unity Engine
1

Latest stable version & newest beta both throw integer overflow when using 3D audio source in webgl build with WA. Could not find any threads on this, so was wondering if it’s a bug or something wrong with my setup?

It depends. Try to post the callstack from a Development build here.

this right? The only thing I change is spatial blend from 0 to 1. Audio listener and source are on separate game objects.
