Start with the symptom, not a global reset
A playback question can concern opening a source, video decoding, sound output, subtitles or display framing. Identify what remains visible and usable, then choose the branch that matches the observation. A resolution explanation alone cannot answer a missing-audio or subtitle question.
Choose the observed branch
Preserve the reference
Record the exact source/title, rendition, device/player and time. Compare one working reference on the same connection, stopping earlier playback before another test. Keep the starting preference before a supported change; several simultaneous changes make the result inconclusive.
