NS_E_WMPCORE_DEVICE_DRIVERS_MISSING
Where the Player stopped
NS_E_WMPCORE_DEVICE_DRIVERS_MISSING is HRESULT 0xC00D10DD. At the playback core device drivers missing checkpoint it means required audio/video device drivers or exposed device capabilities are unavailable to playback; the result belongs to the WMP playback core, graph and media-resource boundary, not to an unspecified Player failure.
An additional test is to record device IDs, driver versions, disabled/problem state and graph renderer failure; that evidence is more useful than reinstalling the Player or changing several unrelated settings at once.
Why the producing component matters
Representative case: The machine exposes no usable audio renderer after a driver removal.
How to prove the condition
- Preserve
0xC00D10DD, the ErrorItem context and the object instance involved in the failing operation. - Confirm the failure directly: record device IDs, driver versions, disabled/problem state and graph renderer failure.
- After you install/enable a compatible vendor driver or choose an available device, recreate the owning WMP object and verify that the corrected generation completes.
Minimum useful incident record
Capture state before Player cleanup:
- What to verify: record device IDs, driver versions, disabled/problem state and graph renderer failure.
- Artifact: play state and transition immediately before failure.
- State: selected graph/source/filter or codec identity and version.
- Object identity: audio/video device identity and driver generation.
- Underlying evidence: ordered ErrorItem queue with errorCode, errorContext and media object.
- Correlation: Player.URL, current media sourceURL and resolved final URL.
Targeted fix
Change the responsible precondition rather than masking the symptom: install/enable a compatible vendor driver or choose an available device.
Neighboring codes to separate
| Result | Different condition |
|---|---|
NS_E_WMPCORE_SOME_CODECS_MISSING | A multi-stream item is missing one or more codecs even though other streams may be understood |
NS_E_WMPCORE_MEDIA_URL_TOO_LONG | The media URL exceeds the length accepted by the WMP core path |
NS_E_WMPCORE_TEMP_FILE_NOT_FOUND | A temporary artifact created for download, conversion or staging disappeared before consumption |
Completion criteria
Keep one fixture that reproduces 0xC00D10DD and one corrected fixture that changes only the identified precondition.
