Dennis,

> If you are running in a graphical environment

I (ofcourse?) tried both the GUI as well as console-based suggestions that I
could find.  Alas, none of them made a difference.

But I remembered having another sd card with the same, but not actually used
OS on it.  It had no problem, using "speaker-test", to output sound over the
the audio jack.   In other words: the only difference is that I used a
default configuration and no extra packages (same KVM config).

On the first I did enable SPI, I2C and Bluetooth, and installed some
packages.   Might bluetooth be causing problems perhaps ?   While pairing
(with a smartphone) I did see something come by related to bluetooth audio
...

And although I've not been able to google anything in this regard, do you
maybe know of a guide or maybe even a diagnostic program for problems like
these ?

While googeling I read it could be (nowerdays by default) disabled, yes (no
mentioning about how to change that though :-\ )

:-)   I ment that as "something build into Python".   I read about a "beep"
function, but that one needed another package to be installed.

I even tried an example that used writing to "/dev/audio", but it wouldn't
work (but didn't throw an error either).  Only when I read that that device
was removed in v3.x I realized I had just been creating and writing to a
simple file. :-|
