So... here's a list (sorry guys):
Main menu -> New Game -> Return: This should be the high (back) click sound, but is the standard low (forward) click sound.
Main menu -> New Game -> Tutorial -> Play now: Should be a low (forward) click sound, but is none.
Main menu -> New Game -> Scenario -> Play now: Should be a low (forward) click sound, but is none.
Main menu -> Options -> Audio | Video | Misc | Newtork | Keyboard Setup: Should be a low (forward) click sound, but have the high (back) one.
Main menu -> Exit: Should be a high (forward) click sound, but is none.
In-game menu: All button click sounds are missing
In the very most of places, multi-option selection boxes (the ones with the arrows to the left and right) do not have any click sounds. They currently do have
some (only)...
- on the Internet lobby screen for the refresh interval selection box
- on the custom game menu when you are connected as a host but only on the readiness-indicator and
- on the custom game menu when you are connected as a client (everywhere then).
I think the multi-option selection boxes should have the low click sound everywhere.
Generally those click sounds are not a big deal, but they are currently incoherent, which doesn't make a great impression.
