Very annoying audio issue on Asrock BeeBox Kaby Lake

Hello community,
I have an Asrock BeeBox Kaby Lake where I use the MVC Kodi Fork (pinned thread). All working fine expecially the 3D feature.

But I have an irritiating issue that is driving me crazy. When I resume the BeeBox from sleep/stanby I, often, got no audio on HDMI. I don’t think the issue is caused by Kodi, because the whole Windows has no audio. The only way is restart the BeeBox.

I tried everithing, update intel and graphics drivers, EDID override, HDMI PIN 19 block (with tape)….. All solutions discovered and tried by me simply don’t work.
I have also another media player in other room (Asrock Visio 3D) and this is not affected by the HDMI audio issue.

Is there any other BeeBox users with the same issue?
