- spotify_init(pcm_cb, event_cb): cspot's data callback hands 44.1 kHz
stereo s16 PCM to the player and returns what was taken; the player's
blocking ring write paces decoding to playback speed.
- Events: FLUSH/SEEK/PLAYBACK_START empty the ring (skip/seek sound at
once); PLAY_PAUSE pauses output (silence, buffer kept, no underrun);
VOLUME logged (applied in b4).
- player: Spotify via its own audio_out converter (44.1 -> 48 kHz);
source_state playing / paused / buffering.
- Verified from a Mac: music on the AES67 stream (10 s: 0 gaps, no
silent packets, RMS -9.6 dBFS, peak 0.0 dBFS), buffer 4.0 s full,
0 underruns, pause/play/skip/seek events.
Seen: first 3 connects "Can't connect to spotify servers", 4th worked.
