maxjivi05 ca5d39b6f5 DirectAudio relay: prime before playing, one consumer, safe buffer floors
- The output stream started before the client had its ring, so every connection
  opened with a run of short callbacks: six clicks per stream on a RedMagic, even idle.
  The callback now plays silence until the ring holds its target, and only a real
  underrun afterwards counts.
- An underrun ends the block with a short fade and waits for the ring to refill to
  target before resuming with a fade in, instead of zero-padding every short callback.
  Each callback spent starved grows the target, so one stall sizes it for the next.
  With a producer freezing 60 ms every 2 s: 14 underruns before, 1 after.
- During a reopen the outgoing and incoming streams could both drain the ring. Only
  the promoted stream reads it now; any other plays silence.
- The ring target starts at 40 ms instead of two bursts (8 ms) and keeps what it
  learned across reopens.
- The device buffer is at least two bursts; 12 ms was a single burst on devices that
  grant a 20 ms legacy stream.
