device removal policy issue

I should probably also mention I also did a clean install of Windows 10 x64 1809, and the issue is present before installing a single thing. The image shown is after all drivers have been installed, same thing.

My system contains CPU of 2400G which contains Vega 11 GPU, and also Vega 64 GPU aw well. BIOS is set to IGP as primary to allow for dual graphics. IGP will not be set to secondary as this will break dual graphics. Thanks for reading, and have a wonderful day!

I suspect that it may be worthy of consideration that in device manager, in the details section, I do note here that the 'Removal Policy' contains the value of '00000002', however I can imagine that '00000001' is the value for devices that shall never be removed in any circumstances whatsoever. I would simply change this value if I could, but sadly there appears to be no way aside from a boot time kludge at every startup.

It does look like that. In device manager though you can see that after those seemingly driverless entries, the actual proper device with driver is shown, as a child of the no name entry.

The issue appears to be simply a windows policy issue, possibly the driver isn't telling windows that the device is non-removable. I wish I could change it.

This issue possibly linked to the following issue:

If so, I would hope that if it gets addressed, no further loss of function occurs. The work-around is to simply use iGPU HDMI audio channel along with dGPU HDMI video channel. It isn't perfect, but if this saves resources, then it does make sense to have lost dGPU HDMI audio channels when running dual graphics.

Having said that, even with iGPU totally disabled, there appears to simply be no way at all to have dGPU HDMI audio. This means that anyone with the 2400G type processor installed and a dGPU card looses dGPU HDMI audio.
