I have an audio level slider and when I slide it down to level 0 and slide back up to some hearable level the audio track starts over from the beginning time.
I used the same slider in 4.10 but it was not like this back then.
There’s a known bug (or maybe it’s intended, but it’s dumb) where soundcomponents get killed automatically when their volume is 0. There’s a bool, VirtualiseWhenSilent, on SoundCues (or maybe sound waves) that you can try to fix this; but I’m not sure if it works. A workaround would be to only slide the volume down to 0.01 or something. Probably couldn’t tell the difference.
