Symptoms

Music is missing from the main menu and during normal gameplay.

Dialogue and sound effects work correctly. Music in the opening cinematic also
plays correctly, but the main-menu music and dynamic gameplay music do not play.

I progressed through the game to the excavation mission where the first artifact
is discovered. No gameplay music played before, during, or after discovering the
artifact.

This was reproduced using Proton Experimental without Protontricks or Winetricks
DirectMusic components.

Launch options used:

PROTON_LOG=1 WINEDLLOVERRIDES="d3d8=n,b" %command%

The d3d8=n,b override is required for rendering compatibility and is unrelated
to the audio system.

The Proton log shows that builtin DirectMusic components are loaded, including
dmloader.dll, dmusic.dll, dmime.dll, dmsynth.dll, dsound.dll, and
dmscript.dll.

During DirectMusic initialization, the log contains:

fixme:dmime:IDirectMusicAudioPathImpl_GetObjectInPath (... IID_IDirectMusicGraph ...): stub

This is immediately followed by:

fixme:dmime:performance_SetGraph (...): to check

and the builtin dmscript.dll being loaded.

At the beginning of the excavation mission, Proton initializes DirectMusic again,
creates a standard audio path, connects the synthesizer to DirectSound, and
activates the audio path. However, no gameplay music is produced.

The separate ALAudio/OpenAL audio system works correctly, as dialogue, sound
effects, and opening cinematic music are audible.

The issue does not cause the game to crash. DirectMusic remains active until the
game exits normally.

The generated Proton log is attached to this issue as:
