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.
