【SYSVAD】: devcon install TabletAudioSample.inf Root\Sysvad_TabletAudioSample failed

[hellomanyi]

I follow step from README.md, Built all related files. then close secureboot and reboot into testmode;

then perfrom " devcon install TabletAudioSample.inf Root\Sysvad_TabletAudioSample" success;

and I find a "!" in "Virtual Audio Device(WDM) - Tablet Sample" item in device manager;

setupapi.dev.log shows: Device not started: Device has problem: 0x27 (CM_PROB_DRIVER_FAILED_LOAD), problem status: 0xc0000263;

I find https://github.com/microsoft/Windows-driver-samples/issues/21 and try "pnputil.exe -a tabletaudiosample.inf", but still failed;

setupapi.dev.log detail:
