Dear Marcus, this was not, as it turned out, strictly a "bug" in Launchpad terms. In fact, as I and my Watcher Raymond discovered from inspired research by a guy whose name I have forgotten, it started life as a deliberate "System Restriction" approved and adopted in the minutes of Ubuntu's Central Committee.
Although originally intended as an emergency remedy to cover the imminent release of the upcoming Ubuntu version, it remained in force over the next _half dozen or so_ releases. The story goes like so;- with HDMI becoming accepted it was intended to include suitable drivers in the next Ubuntu, but with the release deadline looming, it was recognised that the "Radeon" drivers for ATI video cards, were not fit to go. The sound sub-system of said drivers was seen to host a nest of insecticide resistant bugs keen to crash the entire system. The official solution was to go ahead with the release _with HDMI sound disabled_ but leaving the video. It effectively _became a bug_ when, possibly from embarrassment (?), all mention of this was omitted from the "Release Notes" of this, and following versions. There were two workarounds:- 1) select the appropriate proprietary ATI driver & install 2) follow instructions from Launchpad contributors, ignore the risk, and _simply re-enable audio._ I had fun with this at the time. Hope you find it of interest. Regards, Bob On 05/03/2020 13:14, Marcus Tomlinson wrote: > This release of Ubuntu is no longer receiving maintenance updates.

The symptom is the same:- i) turn computer on ii) select "system settings" iii) select "sound" iv) observe that I am presented with only 2 choices for sound "output" ---onboard analogue, or onboard digital; NO HDMI This same symptom occurs with every attempted upgrade from 12.04 Precise Pangolin, whether I upgrade online or from CD ; or erase the entire installation and re-install the later versions fresh from CD (which I often do when out of frustration I have been tempted to load proprietary ATI drivers .......resulting in little pop-ups with AMD kindly informing me that I am mounting "Unsupported Hardware" sic.) NOW:- When ASUS make half the Motherboards on the planet and ATI make half the Graphic cards, then WHY?? , if I choose on account of this prevalence to regard this as a rather general bug and and start writing this report is my computer already telling me that I have to go "unix-nerd" , and open a terminal, and install a program called "pavucontrol" which is a volume control for something called "Pulse Audio" and which as I eventually find instruction; will, if run with no options and no commands, tell me in an extremely frustrating fashion, that somewhere in it's interior it is running my desired HDMI at 100% volume !!
