RuntimeAudioImporter: some interesting bugs

i have three bugs for you.

i should preface by saying im using an ogg file for all this

so the first is a small one (but may be easy to fix). the audio will pop at the start when its played. basically just that. it doesnt matter the play time. its also not that loud.

the second is; on the first play of the audio, if i play the audio from any other value than 0, the editor will crash. if i play the audio (from 0) then stop or pause the audio, the audio will not play again. the editor wont crash, just nothing will happen.

this is my setup for that.

the third is; if i compress the audio, the editor will sometimes crash (about 50/50) without me using the sound wav (ie, crash upon finishing compression). for all the tests iv left quality at 100. changing this doesnt seem to do anything, so iv left it where it is

if the editor doesnt crash upon loading, then it will crash upon trying to play. this used to be not the case, but im guessing an update change something and its causing havoc. even then, it previously would only work under certain conditions (i think compression buffer and fill PCM Buffer would work, but raw wave would not? cant remember. its been about a month)

here are some recent crashes. see if any of them tell you whats going on. heres my blueprint setup

just filling the compression buffer and nothing else
