SAVER_AUDIODRIVERHANG
SAVER audio-driver hang bucket for SAVER_AUDIODRIVERHANG
SAVER_AUDIODRIVERHANG is bug check code 0x0000F400.
This bucket points at an audio stack or audio driver hang in the diagnostic path. Endpoint, APO, miniport, service, and app audio-session state are more useful than the bucket name alone.
How to read it in a dump
- Treat this value as an internal diagnostic bucket from the Windows SAVER family, not as a classic blue-screen stop code with public parameter semantics.
- the useful evidence is the dump type, WER bucket, triggering process, provider-specific data, and event-log context around the capture.
- the symbolic name narrows the subsystem that requested capture; it does not by itself identify a defective driver or application.
What to check
- Check audio endpoint, miniport, APO, Bluetooth/USB audio, and Windows Audio service events.
- Correlate with device changes, sleep/resume, calls, media playback, or exclusive-mode audio.
- Update or roll back audio drivers only after collecting dump and event evidence.
