ACCESS: Martian Memorandum - Adlib Music Volume Broken

[vonmillhausen]

ScummVM Version: Tested ScummVM 2026.2.1git25327-g717e3a4185b, as well as release versions 2026.1.0 and 2026.2.0
Game Language: English
Game Version: DOS
Host OS: Windows 11 25H2 (26200.8246)

Steps To Reproduce:

1. Simply load the game with the default Adlib audio setup (no MT-32, etc.)
2. Note how the intro music is almost inaudibly quiet, but the drum channels (which start during the intro text and continue in your office) are loud. This continues for at least the beginning of the game (office, Terracorp, Alexis' house - I haven't played further)
3. Use the ScummVM volume settings for the game, and try to turn the music up or down - note how it doesn't have any impact on the music/drum volume. "SFX volume" slider does work (e.g., does impact the volume of Tex's footsteps)

I'm attaching two MP3s, one recorded from ScummVM, and one recorded from Dosbox - you can hear that while the drums (towards the end of the recordings) are the same volume in both, the music (towards the start of the recordings) is of normal volume in Dosbox and almost inaudible in ScummVM. Plus as I say, ScummVM music volume slider does nothing.
