Keep PCM and its clock sample in cancellable datagrams so recovery
cannot replay audio buffered before a Wi-Fi stall.
Drop blocked real-time packets with an explicit discontinuity and make
a newer reconnect supersede stale audio authorities.
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.
Give microphone data priority over replaceable clock feedback and
reduce feedback traffic on the shared client-to-host FIFO.
Retry short FIFO stalls outside the realtime thread and coalesce
consecutive packets in the existing fixed Windows buffers.
Avoid one broker write per tiny PipeWire quantum without adding
allocations or intentional capture latency.
Advertise signed and floating-point 32-bit formats across mono,
stereo, quad, surround, 5.1, and 7.1 at every supported rate.
Carry sample encoding through the broker and LGMP protocol so integer
and floating-point streams remain distinct.
Expand packet, shared-memory, and ring capacity for eight-channel
32-bit audio.
Treat the binding phase as the authoritative shutdown state after
graceful stream release.
Cover disconnect while the host drains and unbinds both streams.
Scope the legacy latency offset to classic SPICE and use the LGMP
poll bound as its fixed arrival reserve. Keep learned jitter additive.
Select provider clock feedback only when the current remote endpoint
advertises it, avoiding a failed startup attempt on broker v1.
