Unused sounds

[Wuzzy2]

Version of OpenTTD

1.11.0-dev (4869840)

A couple of sounds are unused:

• SND_0D_STEAM (OpenSFX: steam exhaust sound, like from a steam engine)
• SND_11_CRASH (OpenSFX: light crash sound, less dramatic than the SND_13_BIG_CRASH sound)
• SND_22_CAR_HORN (OpenSFX: empty sound)
• SND_23_CAR_HORN_2 (OpenSFX: 'modern' car horn sound, twice)
• SND_32_POP_2 (OpenSFX: empty sound; note that SND_2F_POP is the bubble pop for the Toyland bubble extraction)

Is it intentional or is this just an oversight?

By the way: If the sounds are really intentionally unused in OpenTTD, I think the corresponding sound IDs should be marked in the source code (via code comments).

OK. I was told by @frosch123 that the sounds are intentinoally unused. I therefore change the issue to this:

• Add comments in source code to mark the unused sounds
