I can’t be sure that this is the only issue, but looking at the screenshot you posted, I can see that the event has no sheets and is not persistent. This means that it will automatically reach a natural end and be stopped as soon as it starts, and so will not be capable of receiving or processing audio.
In the event’s macro controls, set the “Persistent” property to “On.” This will make the event persistent, ensuring it does not automatically stop when it is not playing content.
I also notice that the “player0” group bus’ fader volume is set to 0 dB. As mentioned in the instructions I gave in this post, you would need to set the faders of the buses to -oo dB, or you’d get a duplicate of the signal that isn’t spatialized as well as the spatialized version of the signal.
