Having spent several hours at this today, I've concluded that the problem is caused by the Startpage add-on to Firefox. Specifically, startpage 1.3 and Firefox 71.10. Early in the stepwise setting everything up, I started Firefox, set its typefaces and so on, then installed Startpage. The sound system stopped working instantly. I removed Startpage and the sound came back. A reboot confirmed that no lasting damage had been done. So, I'm now using 'EU Startpage - Unofficial', which seems to working well so far.
It's really weird that a Firefox add-on would cause system-wide sound to stop working!
Anyway, glad that you figured it out Regards, Julien
