3 sounds are not played simultaneously

Hello. I have 3 sounds in my project that should be played at the same time (rain, clatter of wheels and wind). But for some reason, only 1 sound is played (knock of wheels). But sometimes the sound of rain is played, then fades out and plays again. At the same time, the sound of the sound of the wheels becomes quieter. Why is this happening? How do I make all sounds play the same?

And if I turn down the volume of the sound from 1 to 0.7, for example, the sound stops playing at all. Sound works only when set to 1

Hi, the first thing I’d check is Attenuation Settings on those sounds. they might be set too tight, causing the sound to disappear when the listener is too far away.
