This may sound a bit odd, and then again it may not. I have a NUC 847DYE running Linux Mint which I use as an HTPC. Of the two HDMI ports, I can
only get sound from the one nearer to the ethernet port. The other HDMI port produces video just fine but never audio. I've upgraded to the latest BIOS and also tried switching the cable around then rebooting, but without joy. Any ideas?
