If it makes any difference I'm using matlab 7 for linux

I'm searching many files for a particular word and in general its not in there. When nothing is found then for some inexplicable reason the computer makes a beep. This is internal speaker so I can't just turn the volume down.

I'm in a group office so this beeping will be irritating everyone else. How can I stop matlab doing it

How exactly are you doing the searching?

The only beep I have found in the 2008b Linux preferences is for the command line and has to do with matching brackets

Have you considered using !grep instead of searching the files one by one ?

try run 'beep off'. It stops the beep sound afterwards when I type in 'beep'. But it didn't stop the beep sound for 'not found' in Editor on my computer. But I can mute the speaker or plug in a headphone.

I am using MATLAB on Windows. I can go to Control Panel->Sounds and Audio Devices->Sounds and change the 'Sound scheme' from 'Windows default' to 'No sounds'. Then the beep sound from 'not found' in Editor disappeared. So it looks it is depending on the system setting. You might want to see if you can change the system setting on your Linux system.

I'm afraid that was something I tried even before asking the question, it is the same sound made by the beep command but beep off makes no difference

Unfortunately I don't have the option of an external speaker, its a remotely accessed computer that appears to route the sound through the internal speaker by default, my sound is muted

在 MATLAB Online 中打开

I found this link

https://wiki.archlinux.org/index.php/Disable_PC_Speaker_Beep

which suggests that you can unload the pcspkr module.

My MATLAB (r2011a, Linux, 64-bit) does not beep when using search and I do not believe it ever has. Are you sure it is not a setting outside MATLAB? What happens with find in a standalone text editor (i.e., kate or gedit)?

Put a piece of duct tape on it then!:-)

I am still going with disable the internal speaker. Asking the IT person responsible for the computer to disconnect it is gong to be faster than finding what is causing the beep.

Have you tried switching DE (e.g., KDE)? Can you make a new account and see if it happens there also?
