When launching into Minecraft Alpha (Specifically 1.0.15) there is no sound. After waiting for a bit there is still no sound. I set the launcher to stay open and there is still no sound. I changed the compatibility mode settings, however, they will not go down past Windows 8.1

System Specs:
Windows 10 AMDx64 Arch
Java 8
Running as administrator
Attempted to run in Windows XP, Win Vista, Win 7 Compatibility modes - Failed.
