Optional: explicitly (re)starts playbackTime() at 0 - use this if you need an explicit restart point (e.g. looping/seeking). Not required otherwise: the first byte that actually flows through write()/readBytes() anchors it on its own (see updateTime()) - most callers just wire this in as a plain Print/AudioStream target (e.g. PacedVideoOutput::setAudioClock()'s usage pattern) and never call begin() on it directly.

◆ playbackTime()

uint32_t playbackTime ( )

inlineoverridevirtual

Elapsed playback time (ms): the sum of audio duration (sample_rate/channels/bits_per_sample-derived) actually handed to write()/readBytes() so far - see TimeSource::playbackTime(). Purely a running total of processed bytes: never extrapolated by, or otherwise dependent on, wall-clock time (see millis(), inherited unmodified, for that) - so it stalls exactly when the caller stalls (e.g. busy elsewhere in a shared demux/decode loop) instead of continuing to advance. Returns 0 before the first byte has ever been processed (begin() is optional - see its own comment).
