Hdmi audio driver, most of the time don't recognize input capabilities

The main problem with my R7 260x and Hmdi audio driver it's that sometimes it can't recognize the Hdmi input capabilities of my Marantz SR5009 Avr.




If I start my WIndows 10 when Avr is already turned there is no issue and I can read the 8 ch. and the compressed format supported




If I turn on the Avr when Windows 10 is already started most of the time I got only 2ch and no compressed format supported.


If I disable an d re-enable the "AMD High Definition Audio Device" device I can fix the issue without restart Windows.

But It's not comfortable


I've this issue since a long time, I bought this avr in February 2015 I'm not sure, with Catalyst, there are no problems.
