Has my map hit the concurrent sound limit?

Hi - I’ve been making a huge map with loads of sound emitters all around it (they’re called using Lua, using sound.Play on the client) and it seems as though I have too much memory taken up by sounds due to this, because after a few more sounds are loaded into memory (i.e. long ambient sound, or custom addon vehicle playing large engine sound) - the sound will go away and the framerate will drop.

It appears making the sound short and smaller file size (instead of 7mb) it fixes, but, is there a way around that?

Thank you
