So, I have to MetaSounds where this problem occurs. Both of them doesn’t get triggered on the On Play-trigger. Instead they get triggered from code. So I spawn on of these Metasounds and they are silent until they get triggered via my custom triggers.
But I assume this is since 5.2, both these types of MetaSounds sound totally broken - like a really loud sawtooth synth.
There is one odd way to circumvent this - and that is to turn of Volume Attentuation inside the attenuation settings on these MetaSounds. Odd.
Any one else that have encountered the same bug?
