Hi again,
We have tried the NUC on all the AV receivers we have available in our labs and are unable to reproduce the problem that you're seeing. The graphics team believes it may be specific to the specific Denon receiver model that you have (unfortunately, we do not have one of those).
In regards to the audio problem you encountered with the latest graphics driver, it's possible that the Intel HD Audio driver might not have installed well. Please try the following:
- Uninstall the Intel HD Audio driver from Device Manager and select checkbox to remove the driver files.
- Uninstall the graphics driver too.
- Then re-install the graphics driver version 15.31.9.64.3165, which will re-install the audio driver.
Regards,
Lois
