Game not run if you try to remove "-nomusic" argument

The game freezes if you try to remove the "-nomusic" argument from the carmack.js file.

I'm trying to reproduce the Doom as IS using a original WAD from my copy, but i can't enable the music on the game.

Can anyone help me with this?

Start by reproducing the freeze after removing the "-nomusic" argument from carmack.js with the original WAD described in the issue. Trace how that argument affects music initialization and compare the behavior with the argument present. Done means the game starts and music can be enabled without freezing.
