The audio processing stage involves mixing two audio streams based on a predefined gain setting. The mixed audio in AXI-S format is forwarded to the DisplayPort source controller and the PL. A small holding buffer that supports AXI-S is used to handshake with the PL. The audio channel does not accept any back pressure from the PL interface. Refer to Table: PS-PL Signals for the Live Audio Interface for live audio interface signals.
