Failed to initialize "[MUSIP_ID not defined]" for music playback

Hello guys,

I just started the doomsday engine and a notification appeared on the top right. The following message:

[WinMM] CD playback error: An unknown error was encountered while loading the specified device driver.

Any ideas of how can I solve it? I just met Doomsday Engine. Running on a notebook with Windows 10.


  • On Windows, Doomsday comes with a music backend for CD drives. This is pretty old-fashioned nowadays; I assume your notebook doesn't have such a thing.

    If you open Doomsday's Audio settings in the Config ⚙️ menu, there is a subsection for configuring the backends. Try selecting "Disabled" for the "CD Plugin".
