Hello
I am using the forge installer-win 10.13.3.1395 on a clean 1.7.10 minecraft installation.
The Startup stops on the mojang splash with:
"Loading - Initializing Minecraft Engine"
"Rendering Setup - Render Global instance".
If I close the launcher it is stuck on:
"[sound Library Loader/INFO]: Sound engine started".
So I tryed around if changing the sound devices does anything and find out that without
any active sound devices MC starts just fine. Even a heavily modded version.
Prior to this version I used FML 10.13.2.1291 without the sound related problem.
