Jack-in-the-box zombies audio not playing

While playing survival endless one of my biggest fears were the jack-in-the-box zombie, as if i get bad RNG he may blow up extremely early and destroy some of my plants. One of the main features of this zombie is to play a little tune as he winds up his box, this is a vital mechanic as if he is blocked by other zombies as he often is in survival endless or in the fog you would have no other way of knowing he is there. Now, I've only experienced this glitch in survival endless but sometimes the audio does not play. I'm assuming that this is because there's a limit to the amount of audios playing at once, since that's usually why audios don't play in video games. While this is just speculation and I don't really know why, but it's still and issue and I would appreciate if this gets fixed, thank you.
