Sorry I have no SP development experience and don't know how to trigger sound play in SP. Here's my code for trying to play a sound after MP Siege starts, but it doesn't work, hopefully it do help for you.
It's been 2 months and the bug is still there. When can you fix this? Is it a tough job?
We have been waiting for dlss to be fixed. Will version 1.1 be made positive this week? Multiplayer games require DLSS
"Fixed a bug that caused a crash on custom servers if they didn't have "MultiplayerForcedAvatars" folder created."
