Retrieve number of channels in Event in Unity

Unity
1

Hi,

How do I retrieve how many channels a StudioEvent has? i.e. Whether it is mono, stereo, or 6 channel etc?
The event in question is “2D” and has no 3D panner attached.

I can retrieve the ChannelGroup from the FMOD.Studio.EventInstance, and then call group.getMixMatrix(nulll, out outchannels, out inchannels, 0);
but it always return 6 and 6 for both inchannels and outchannels (because i’m working in 5.1 speaker mode).

So what is the correct way to retrieve the number of channels in the sound itself?

Thanks in advance,
MM
