Audio Sound Effects cutting out after a lot of them are triggered

I have an AudioSource pool system that assigns an audio source to each sound that will get played.

The system has worked fine when 50+ collectible items sound effects are triggered. However, I also have bullet collision effects, and even though less 10-20 collision effects are triggered, they get cut off when too many are present.

My sound effects are in a mixer group called "Sound Effects" with only the attenuation property attached.

Anyone familiar with this

 

Go to Edit -> Project Settings -> Audio and check how many maximum voices you have set!

If more sounds try to play at the same time than the max real voices value then some will get cut ...

Also you shouldn't have too many sounds playing at once anyway!! It would be too much information overload to the player!
