So I'm on 17.10 (unstable) and I still have issue with this. But its not the same issue.
Now it simply do not show up in the gnome sound settings. To get 5.1 ac3 output I first need to start pavucontrol then in the Configuration tab select the correct profile in the Built-in Audio section. Then it shows up in gnome sound setting. But it does not remember it so I have to to this over and over. So different problem but still an issue. now its showing up in pulseaudio but not in gnome audio. -- 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/1607875 Title: pulsaudio not showing a52 device Status in pulseaudio package in Ubuntu: Incomplete Bug description: so I have a external decoder that is connecting over a optical SPDIF link.
