I am observing an issue during repeatedly cold booting the system over a
long period of time.
The audio device in sound panel is shown as disabled.
When I check the registry for the device under
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\
"DeviceState"=dword:00000004

If I manually change the device state to 1, device is shown in control
panel again.

Also, if the audio service and audio endpoint builder service are stopped
and started again, the issue is gone.

Has anyone observed something similar.

I have checked that the driver is reporting the correct jack state to os
when queried
