UE4 FMOD sounds not working on GoogleVR Daydream

Unreal Engine
1

Is anyone using UE4 4.13 + FMOD for Google Daydream? It works in the editor with mobile preview, but when it’s deployed to the device, I hear no FMOD sounds. It appears that all the library files, fmod.jar, libfmod.so, libfmodstudio.so, libgvraudio.so are being correctly packaged up. And it looks like GameActivity.java is loading the fmod and gvraudio libraries. Here’s a snippet of GameActivity.java:
try
{
System.loadLibrary(“fmod”);
}
catch (java.lang.UnsatisfiedLinkError e)
{
Log.debug(“libfmod not loaded and required!”);
}
try
{
System.loadLibrary(“fmodstudio”);
}
catch (java.lang.UnsatisfiedLinkError e)
{
Log.debug(“libfmodstudio not loaded and required!”);
}
try
{
System.loadLibrary(“gvraudio”);
}
catch (java.lang.UnsatisfiedLinkError e)
{
Log.debug(“gvraudio not loaded and required!”);
}

I tried looking at the adb logcat output, but there’s only one entry for fmod,
I fmod : FMOD::supportsLowLatency : Low latency = true, Pro Audio = true, Acceptable Block Size = true (192)
Does anyone have any suggestions about how to proceed? Thanks in advance for any help.

I might have been running adb logcat with some bad parameters. Here’s the FMOD output from a clean run of adb logcat (looks like Gvr Audio Listener Plugin is missing, so that’s probably Google’s problem):
--------- beginning of main

--------- beginning of system
