Replace the single-owner PCM queues with one shared LGMP SPMC stream. Give each admitted client reliable state and an independent playback cursor, while clients without clock authority resample locally. Extend the audio protocol with per-client epochs and barriers. Keep capture exclusive and bound authority backpressure so slow secondary readers cannot affect the disciplined low-latency path.
