Hello! We have two NUC8i3BEH connected via HDMI to the monitor. And we have constant problems with sound. The sound is periodically turned off, the red cross lights up in the volume settings, it does't find any sound output devices. It helps only to restart the computer. Tried to update the BIOS, reinstall the driver, but nothing helped. What else can we do? We have a lot of NUCs, but only two have this problems.
