[HadeanLake]

Describe the bug

both gcc-14 and clang-18 linux tiles no sound builds fail with:
Error: src/sdltiles.cpp:3726:9: error: use of undeclared identifier 'sound_init_success' or src/sdltiles.cpp:3726:9: error: ‘sound_init_success’ was not declared in this scope
Probably caused by #76782 . Clang 12, Ubuntu, Tiles, ASan failed with same error

Additional context

it is declared inside #if defined(SDL_SOUND) block. I guess wrapping this one use as well is a reasonable fix for this fix this. Declaring it outside of that block does not make sense
