How to disable beep on backspace. Beep off does not work.

I loaded Matlab 2023a this morning, and discovered that it had started beeping in a variety of ways, all of which are incredibly annoying. This never used to happen, so imagine my surprise when I search the problem and discover that people have been complaining about this very issue since at least 2012. I don't know why this has suddenly become a problem, but it is infuriating. I know it sounds like a minor issue, but it has hamstrung my productivity entirely.

The command beep off does not do what it says on the label, leaving the annoying beeps on. If there is any solution that I may have overlooked in my search, I would be most appreciative.

Disabling the system sound in question has had no effect. Matlab ignores my system preferences and plays the sound anyway.

Hacky workaround: I deleted the system bell sound and rebooted, which caused Matlab to go looking for another sound. It defaulted to the freedesktop theme, which I do not use, so from there, I replaced the bell sound with silence. Without completely rebooting, it was still using the same system sound, so it's storing a copy of it somewhere. If anyone knows where that is, or what exactly it is doing, maybe that's a pathway to a better solution?

Hi Soren,

One approach is to directly modify Matlab's sound settings to ensure that the beeping sounds are disabled effectively. Here is a step-by-step solution to resolve the problem:Open Matlab and navigate to the Preferences or Settings menu.Look for the Sound or Audio settings within Matlab.Disable all sound notifications, including beeping sounds.Save the changes and restart Matlab to apply the new settings.By directly modifying Matlab's sound settings, you can ensure that the beeping sounds are effectively disabled within the application.

Please let me know if you have any further questions.

Hi Umar,

I have been unable to find any sound or audio settings within Matlab. There are none that I can see within the preferences menu, and none that I have found elsewhere. Could you please explain in more detail how you arrived at the sound settings?

Hi Soren,

The older version of Matlab had these settings. I do apologize. It was under Preferences-> keyboard. Please see attached. I was told that newer version had these settings located under Preferences. If you want, I can ask some of the moderators for advice to resolve your problem.

Hi Umar,

I'm afraid I have had no luck with that, and my temporary fix has come unstuck. I will see about making the temporary fix more permanent, but having seen that this has been a problem people have been complaining about for over a decade, it's really frustrating that this function doesn't have an off switch.

Thanks for your help.

No problem, Soren. Thank you for bringing this issue to our attention. I apologize for the inconvenience it has caused you. I understand your frustration with the lack of an off switch for this function, especially considering that it has been a long-standing problem.

I have fixed this issue. This was not an issue with MATLAB, but with Linux. I am using KDE Neon 22.04. The problem was caused by an accessibility feature enabled during the last update. To fix this problem, go to Settings -> Accessibility -> Audible bell -> Disable.

Hi @Soren Smith,

Glad to know that it was operating system causing the problem and got resolved. Please let me know if you have any further questions.
