BURIED: Volume controls other than "Mute All" do not work

[Thunderforge]

The only volume control that affects Buried in Time is "Mute All". I expect that all the controls should work.

Reproduction Steps

1. In ScummVM, go to Options… → Volume
2. Check "Mute All"
3. Click "Apply"
4. Start Buried in Time.
5. Expected Behavior: Music sound effects and speech will all be off
6. Close Buried in Time
7. In ScummVM, go to Options… → Volume
8. Uncheck "Mute All"
9. Set "Music volume", "SFX volume", and "Speech volume" to 0
10. Click "Apply"
11. Start Buried in Time.
12. Unexpected Behavior: Music, sound effects, and speech are all at full volume
13. Close Buried in Time
14. In ScummVM, go to Options… → Volume
15. Uncheck "Mute All"
16. Set "Music volume", "SFX volume", and "Speech volume" to 256
17. Click "Apply"
18. Start Buried in Time.
19. Unexpected Behavior: Music, sound effects, and speech are all at full volume, and just as loud as they were when set to 0

I ran into this because I thought that the music was too loud and was drowning out the voices. I tried turning down the music, but it made no difference. I eventually found that none of the volume controls were responding, except for Mute All.

Also found that setting Options… → Audio → Preferred Device to "No music" has no effect.

This would be nice to have fixed before the release.

[NMIError]

Volume control has been added.

Due to the nature of the sound code for this engine, the different volume controls do not represent the types of sound in the game exactly:

Ambient (music, environment sounds): music
AI voice: speech
Effects, interface, footsteps, movie audio: SFX

The movie audio is pre-mixed music, speech and SFX; only the overall volume can be controlled using the SFX volume control.
