No worries at all
I am using the Godot Fmod GDExtension: Godot Fmod GdExtension
And also here is the GodotSteam extension docs on voice chat: Voice - GodotSteam
So far we have voice chat working using regular Godot AudioStream3D nodes. However it is just when trying to pass that voice chat buffer data into FMOD that is proving to be tricky
Thanks for taking a look
