Sorry for lack of info in previous post .

OS : Windows 10 64-Bit
Video Card : GTX 1080 FE
RAM :16GB

I tried all 3 games just to verify that it wasn't just Marathon 1 , all games have no sound running this build of Aleph One on Windows.
On Linux sound is present.

I did a fresh boot of the new build , and no sound at all.
Nothing in the log file at all.

Either way , great to see a new build underway.

Yep , found that out right after i posted .

The editor crashes upon opening a map with M1 Flags .
here is a screenshot of the error.
