When live audio is selected on stream1, irrespective of stream2, the channel status (C), user bit (U), and validity (V) metadata are considered from thelive data input. Because 16-bit non-live audio does not carry the channel status (C) metadata, user bit (U) bits are used from the registers. The parity bit (P) is internally calculated and inserted in the audio sample as audio mixing can change the incoming data parity. The use-cases in Table: Audio Metadata Use Cases are supported for metadata insertion.
