TINSEL: Discworld volume settings don't affect sound, except mute all.

[i30817]

As mentioned, I tried to set the music volume in the Discworld 1 CD version to zero to listen to background music and I noticed that it didn't affect the sound.

Then I tried to set all 3 bars to zero. Same result. Mute all did remove the sound.

Scummvm version 2.7.1 18 July 2023. Android 10, a Lenovo tablet I'm forgetting the model.

If I restart the game after setting music to 0, sound did behave a bot strangely. I hesitate to say how because it's been two days of not thinking about it, and it's probably best you check it yourself, but I sort of kinda remember voiceovers off, not music.

This issue was brought up on the ScummVM forum here: ​https://forums.scummvm.org/viewtopic.php?t=17264

and it's not affecting only Android. It's present on the Windows (Win 10 x64) release of 2.9.0 and Windows dev build of 2.10.0git from recent master HEAD.

These are my findings, copied from my reply to the above linked forum thread, from quick testing on Windows:
From quick testing it seems that:

• The volume settings from the in-game ScummVM menu (GMM) do not affect music, SFX nor speech volume at all, and are also not synchronizing with the settings from the in-game menu about volume. However, the "mute all" checkbox does mute all sounds and music.
• The volume settings from the in-game *native* menu do affect volume level for SFX and Speech but *not* the volume level for music.
