I’m using 64 voices, FMOD v 1.06.11 and Unity 4.06.  
Even though we have 64 voice limit, sometimes we hear some interruptions: the sound is “dead” for some frames and continues like nothing happened. FPS stayed at 30~40, without any noticeble freezes.

Check out the screenshot for the profiler right where the problem happens:

I’m also wondering why sometimes we have spikes on the cpu. (check the profiler just before 4:11). Any ideas what might be causing this?

Unfortunately, it’s impossible to tell just from that image what your project is doing. Could you please provide us with more detail about what your game project is doing when the ‘death’ occurs?

Are you able to send us a copy of your project that includes the affected profiler sessions? We need more information to if we’re to work out what’s happening.

That’s the thing: looks like it happens at random places. I tried triggering the same events, but couldn’t replicate the “death”. Looks like things that happens when a garbagge collector appears but you know… FMOD isn’t c# xD

So, it is just a normal run. In most machines it doesn’t happen, but this happens on our game low spec machine.

The only thing that i could think of it’s snapshots: There’s some reverb zones that might overlap each other, and each one has events with distance attenuation and trigger behaviour based on distance.

Here’s the low spec machine:
