NS_E_NO_AUDIO_COMPAT: the failing boundary
NS_E_NO_AUDIO_COMPAT (0xC00D1BB1) means You must specify at least one audio stream to be compatible with Windows Media Player 7.1. The important boundary is legacy player profile compatibility; do not replace this result with a broader “Windows Media failed” diagnosis.
What this result proves
This code proves that the profile has no audio stream even though Windows Media Player 7.1 compatibility requires one. It does not, by itself, prove a codec, permissions, network, device, or media problem outside that boundary. Preserve the first lower-level result when one exists, because later Player or Encoder errors can hide the original cause.
Evidence and focused verification
Record stream list and target compatibility level; add one supported audio stream or remove the legacy compatibility requirement. Keep the media object, endpoint, profile, or device identity fixed while changing only that rejected precondition. A successful retest should pass this exact boundary; a different HRESULT from a later stage is new evidence, not recurrence of NS_E_NO_AUDIO_COMPAT.
