STATUS_HDAUDIO_NO_LOGICAL_DEVICES_CREATED
The codec was detected, but no endpoint device could be built
An HD Audio controller and codec can enumerate successfully at the bus level while the function driver still fails to create render, capture, modem, or other logical subdevices. This status means every attempted subdevice creation failed or the parsed topology exposed no valid function group for Windows to publish.
Likely evidence lies earlier in enumeration: invalid codec responses, missing pins or converters, failed child-device creation, resource allocation, or an incompatible codec-specific driver package.
What to inspect
- Enumerate codec function groups, widgets, pin defaults, and converter nodes from raw responses.
- Find the first failed subdevice creation rather than diagnosing only the final aggregate status.
- Check Device Manager problem codes, PnP events, INF matching, and audio service endpoint creation.
- Test after cold boot as well as resume to identify codec power-state initialization defects.
