When I have over 60 or so sounds in my game, even if they are STOPPED, any additional sounds that are added will not play. I tried to increase maxchannels with:

FMODUnity.RuntimeManager.LowlevelSystem.init(1000, FMOD.INITFLAGS.VOL0\_BECOMES\_VIRTUAL, System.IntPtr.Zero);

But that didn’t seem to change anything. Anything else I can try?

EDIT:  
I also tried and failed:

```
    FMODUnity.RuntimeManager.LowlevelSystem.setSoftwareChannels(256);
    FMOD.ADVANCEDSETTINGS settings = new FMOD.ADVANCEDSETTINGS();
    settings.maxVorbisCodecs = 128;
    FMODUnity.RuntimeManager.LowlevelSystem.setAdvancedSettings(ref settings);

```

EDIT 2:  
To recreate, all I have to do is this inside an ienumerator:

```
   var sound = FMODUnity.RuntimeManager.CreateInstance(path);
   for (int = 0; i < 100; i++) {
           sound.start();
           sound.release();
           yield return new WaitForSeconds(0.05f);
    }

```

After that new sounds will not play anymore.

You need to make sure fmod’s update function is called to allow it to manage and release channels.

You don’t need to adjust any settings, so I would remove that code you added (ie in FMOD\_ADVANCEDSETTINGS) unless you want higher CPU usage.

A tight loop like you’ve done doesn’t allow the update to run, so is an artificial test.
