Ah, I see - this looks like a different issue. Let me paste the relevant section of the Troubleshooting thread here. If you do decide to go the route of deleting dll files in your Windows/ folder, please be extremely careful.
I would not recommend trying that part of it unless you feel comfortable with it.
The game crashes when run with sound on, "Fatal: null", "Error in sound initialization", "org.lqjgl.openal.AL10.nalDistanceModel(I)V"There can be multiple causes of this issue.
Running the game with sound on but with no sound output device plugged into the computer (i.e. speakers or headphones) can cause this issue. Running with sound turned off from the launcher will get around it.
After that, the first thing to try is to go
here and download and run the OpenAL installer, then reboot and see if it helps.
Running the game as administrator (right click icon, "Run as Administrator") may also help.
If these do not help, search for OpenAL32.dll and OpenAL64.dll in your Windows/ folder, and (very carefully) delete them. Then restart your computer and try running the game again.
Finally, if this does not help, copy these files from starsector-core/native/windows to Windows/System32, reboot, and try again.
