An active feedback connection was detected in the voice graph, with an Audio Objects bus as the destination. Feedback connections for Audio Objects buses are not suppported. Therefore, we recommend that you change the bus configuration to one that performs a mixdown of its input connections, such as "Same as Main Mix" or a specific speaker configuration. Alternatively, if the feedback connection was not the result of a complex audio propagation or spatial audio setup, you can try to avoid the situation that created the feedback connection. Feedback connections usually occur due to certain emitter-listener relationships creating cycles in the voice graph.
