Since removing and reinstalling several driver versions using the full DDU package i'm having an issue I cant solve where the following happens.
Each time I reboot my HDMI audio device shows a red cross and nothing is selectable in there, audio seems to work however but I cant tell if its set to stereo or 7.1 as it should be. To resolve this I have to right click and trouble shoot, this then brings back the device. The annoying thing though is it sets it to default to stereo so I have to change that as well.
I've tried capturing the REG keys and having those merge at logon but that doesnt work either. I've done a full DDU uninstall and that also failed, rebuilding my OS is NOT an option so i'm hoping someone has a fix for this.
