ocaml
sound command is not working
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?
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?
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
