sound command is not working

[Neutralino2007]

It seems that the sound command is not working.
It produces no sound even if executes from multiples OS with diverse Ocaml installations.
Is there a specif reason or is this just a bug?

Hello, thank you for your report. However, precise reproduction instructions are needed in order to investigate any issue: what exact system are you using, how exactly did you try to use Graphics, what was the output (if any), etc.

I ran my code on VSCode which is installed on virtual machine powered by Debian.
Whenever I tried to execute the sound command, the code would compile correctly with no errors or abnormal output.
It would just not produce the sound.
I checked everything audio parameter and configuration and everything is fine.
The problem really seems to come from sound if I'm not mistaken.
Have I given enough data?

Did you open a graphics windows before using Graphics.sound?
How is the system bell configured in your system?
Can you hear the system bell?

[Neutralino2007]

I opened a graphic window before using the command.
I can hear the bell if testing the sound with speaker-test tests this parameter.
How can I check the bell configuration if it's not this?

[Octachron]

As far as I can see speaker-test does not have an option to test the system bell?
You can try

echo -e "\a"

in a terminal.
However, it is important to note that Graphics.sound is not really a useful function; and I would be in fact in favor to deprecate it.

Graphics.sound might still work under Windows, but the X11 implementation based on XBeep seems to have stopped working a while ago. With Ubuntu 22.04 and with macOS, I get a standard terminal beep, but pitch and duration are ignored.

(For Ubuntu: remember to un-mute "System Sounds" in the Sound settings.)

Ok, thank you very much for your answers !
I took into account what you said. However, I confirm definitively that it's not working for Debian...
If Graphics.sound is not working, I'll, maybe, search for another solution if it exists.
Thanks
