I was slightly surprised to see the word "Broxton" since Intel canceled that product line before it was ever released. However that just seems to be an incorrect label arising from multiple Intel product lines sharing chipsets... The system is really a J3455 (Apollo Lake) and shares some silicon with the Broxton line.
Still, since you have a very new system you might find success in using a newer kernel. So try installing package 'linux-image-generic- hwe-16.04-edge'. If that does not solve the problem then please try the very latest from here: http://kernel.ubuntu.com/~kernel- ppa/mainline/v4.12.8/ -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1709708 Title: Intel Broxton HDMI, Digital Out, HDMI] Pulseaudio detects output but produces no sound on NUC6CAYH Status in pulseaudio package in Ubuntu: New Bug description: Upon bootup, the HDMI output connected to a Samsung TV shows up as an output. If this output is selected and a sound test run (either using the GUI or using aplay /user/share/sounds/alsa/Front_Center.wav) no sound is heard. Pavumeter does however show sound coming through. I found that sound can be fixed by allowing the display to sleep, waking it up, and then restarting pulseaudio (pulseaudio -k). After that sound output through HDMI to the TV will work until rebooted. The fix can be succesfully scripted as follows: xset dpms force off sleep 1 pulseaudio -k The machine is an Intel NUC6CAYH, connected to a not particularly new Samsung 42" TV using an HDMI cable, running a fresh install of Ubuntu 16.04. In earlier attempts at fixing the issue I set pulseaudio to never let the sound device sleep (commented out load-module module-suspend-on- idle in /etc/pulse/default.pa), and also set the default sampling rate to 48000 (default-sample-rate = 48000 in /etc/pulse/daemon.conf). Not sure if these settings contributed to the fix, but they are not sufficient on their own.
