Can't play multiple sounds at once

I made some fireworks and when i shoot 1 firework it makes a sound when it explodes but when i shoot 10+ fireworks and it explodes there is no sound or sound is really bad. Why is that? and i have multiple audio sources.

@Llama_w_2Ls i have PlayOneShot but the problem is that if i shoot multiple fireworks the sound just stop even if all the fireworks have there own audio source.

Look into sound managers, there a re a few free ones on the asset store.

see Unity - Manual: Audio Mixer
“The Unity Audio Mixer allows you to mix various audio sources …”
