for firefox from v52 onwards pulseaudio should work and it is the preferred linux sound system
alsa & jack don't work and need a locally built from source version of firefox
I use jack so I need the alsa system until the native jack is fixed
Thanks, Steve. A second evening of perseverance revealed the deeply hidden secret. The "Sound & Video" -> "PulseAudio Volume Control" menu item has only 3 widely spaced tabs, underutilising the available space, and the "Output Ports" tab offered no management/configuration possibilities. But there are two tiny dark triangles in the corners, and clicking on the RH one leads to an extra hidden tab, "Input Devices", and clicking again reveals "Configuration". There, in a "Profile" selection box, it is possible to select "Digital Stereo (HDMI) Output". Once selected, it even seems to be the power-on default. (Much to my surprise, given the user-hostile perversity of the devious GUI design.) Granted, the purpose of a GUI is to put access to necessary functions at the end of deep maze rat runs - but invisible secret tabs with double blind access?! I do believe that some of these devs are being paid by Microsoft to paralyse linux. (If not, we know that they were born arse-backwards, and have never turned around.)
