Hello Acren,
I was unable to reproduce your issue on our end using the repro steps you have provided. I have a couple of questions to help narrow down the issue you are experiencing.
- Do you have a project you could provide where this issue occurs?
- Does this issue occur in just 4.16 for you, or does it occur in other engine versions?
- does this issue occur if you do not use the Master sound class?
Thanks!
