NS_E_DVD_NO_AUDIO_STREAM
Where this result occurs in the Player workflow
NS_E_DVD_NO_AUDIO_STREAM (0xC00D116B) marks finding and connecting an enabled DVD audio stream. Keep this HRESULT attached to the producing operation even when the Player shows a broader message.
Mechanism
Successful reading of files from the DVD volume does not prove that the navigation program, decoder graph or protected output path can be used. A representative way to reach this result is that the current title has no enabled audio stream compatible with the graph.
State snapshot
| Evidence | Why it matters for no audio stream |
|---|---|
| Producing object and operation | disc path and media generation, DVD domain, title/chapter, region values for disc/drive/decoder, selected audio/video/subpicture streams, decoder CLSIDs, renderer and display mode, protection negotiation result and first DirectShow HRESULT |
| Key observation | available audio streams, selected language/format, audio decoder and renderer state |
| Controlled comparison | Repeat the producing call after changing only this condition: select an existing audio stream and working decoder/output device. |
Controlled diagnostic sequence
- Capture
0xC00D116B, the exact Player/API operation and the first timestamp at which it appears. - Save available audio streams, selected language/format, audio decoder and renderer state; do this before ejecting media, reconnecting a device, canceling a job or rebuilding the Player object.
- Correlate the result with disc path and media generation, DVD domain, title/chapter, region values for disc/drive/decoder, selected audio/video/subpicture streams, decoder CLSIDs, renderer and display mode, protection negotiation result and first DirectShow HRESULT.
- Reproduce once with the original source and destination, then apply only this change: select an existing audio stream and working decoder/output device.

Focused correction
For this occurrence, select an existing audio stream and working decoder/output device. Recreate only the object that produced it and repeat the original operation against the same controlled input.
During verification, do not bypass region or copy-protection checks; diagnose the supported playback path by preserving the exact disc, drive, decoder and display connection involved.
Audio-stream evidence is independent of DVD video
A DVD title can expose a valid video pin while the selected audio stream is absent, disabled or unusable by the current graph. Record the number of audio streams reported for the active title, the selected stream index, language code, coding mode and whether the navigator enabled that stream. Then record the decoder input subtype and the renderer endpoint. This separates a navigation-selection problem from an audio-decoder or output-device problem.
| Observation | Audio-specific conclusion |
|---|---|
| The title reports no audio streams | The disc/navigation structure is the first boundary; installing another video decoder cannot create an authored audio stream. |
| An audio stream exists but its decoder pin will not connect | Compare the stream coding mode with the installed audio decoder’s accepted media types. |
| The decoder connects but the renderer does not | Inspect the selected audio endpoint and negotiated PCM format rather than DVD title selection. |
