No sound on NUC D54250WYKH

Hi,

I have a NUC D54250WYKH connected to my receiver vi the mini HDMI port. The receiver is connected to my Philips PFL8808 55" TV using HDMI cable.

My NUC is running Windows 10.

Each time I turn off my receiver, I'm getting an "X" on the sound driver on the taskbar (see attached image) and the sound card is disabled.

I have to restart the NUC in order to resolve the issue.

Any ideas why or how to fix?

Thanks!

Idan.
