The background music can be placed on the page using the "Video and Audio" object, but it depends on the browser and its settings whether the music can be heard.

You can find my test page with background music at ...

>> https://findelinks.de/go-blogseite/galerien.html

There is also a description there of how to play background music in different browsers, but the description is in German, perhaps you can translate it with Google.

My problem is that I have still an audio clip playing, but there is no Video & Audio object on the page!  It was there at one time, but it has now been removed.  I have cleared out everything on the web server, in case there was some residual code there, and have reloaded the entire website but the audio is till playing when the page launches. I am truly mystified!

It could be that the old page with the music is only in your browser's cache, in which case the browser cache would need to be cleared.

Otherwise, provide a link to the page with the music so that the helpers can search for the code for the music in the source code.
