According to the Steam Audio forum on steam and this topic here Steam Audio seems kinda dead to me; no response from the devs anywhere.
Do you have a direct contact to the devs and is this plugin still in development?
I have seen that there is an actually old pull request for a more recent SteamAudio version, but the bug described has not been listed anywhere (haven’t tested it yet).
Were you able to reproduce it with the steps I mentioned? I also use seamless travel I think, not sure whether that actually affects anything.
I was able to reproduce it in a fresh UE 4.19 launcher project tho.
I am not sure currently whether it actually make sense to wait for an update or toss the Steam Audio occlusion and reverb completely, switching to the plugin [USER=“434”]BrUnO XaVIeR[/USER] created for occlusion and the stock ue4 reverb.
I know that steam audio is a beta plugin but I did expect better support by valve tbh.
