I can't download the image from the Intel site. But the HDMI audio works pretty well on my NUC7 board both for Sumo and master branch. The following are the steps I used to validate the HDMI audio on my NUC7 board: 1. Configure the default soundcard and device: root@x8664:~# cat /etc/asound.conf # Global alsa-lib configuration pcm.!default{ type hw card 0 device 3 } 2. Unmute the S/PDIF by using the command 'alsamixer -c 0'
followed Kevin's instruction. now able to audible on HDMI port.
