We have a problem that the sound will choppy. It only appears in the use of Bluetooth headset. We found a similar problem in Unity Community Support([https://forum.unity3d.com/threads/android-sound-problem.359341/](https://forum.unity3d.com/threads/android-sound-problem.359341/)). But the problem seems to have not been fixed. Is there any way to solve it temporarily?

Unity：5.4.2-GVR11  
FMOD：1.08.12

You could try changing the buffer size to reduce latency.  
[https://www.fmod.org/docs/content/generated/FMOD\_System\_SetDSPBufferSize.html](https://www.fmod.org/docs/content/generated/FMOD_System_SetDSPBufferSize.html)

Add at RuntimeManager.cs, line 220:  
lowlevelSystem.setDSPBufferSize(256, 4);
