No sound with Reverse Warn and soundscape.

The text may be strange because it uses machine translation.

When I was making a mod, I found out that there was something called Reverse Warn and tried using it immediately, but I was not satisfied with the beep sound of the track, so I tried to use a custom sound, but there is no sound.

Another problem is that soundscape cannot be used.
soundscape does not use custom sounds.

I repeated trial and error, but I couldn't solve it.

I will post a sentence.
