How to: Disable or change login sound in Linux Mint 13

In my opinion, the login sound of Linux Mint is quite annoying so I believe many people would want to disable or change it. Although the method to disable login sound in Ubuntu 12.04 does not work in Linux Mint 13, there is another very easy way to do the task.

To disable the login sound in Linux Mint 13 (both MATE and Cinnamon), you just need to open the menu and go to the Control Center. In the Control Center window, select the Login Window option:

You then will be asked to enter the root password. After that the login window will appear and you will need to go to the Accessibility tab. On this tab, you just need to uncheck the two boxes of the Login Screen Ready sound and Login Successful sound. Reboot and you will not hear the login sound in Linux Mint 13 anymore:

In case you want to change the login sound, it is even easier to do so in Linux Mint 13 than in Ubuntu 12.04. You dont need to edit any file at all, just click on the sound box on the Accessibility tab and you can select any new sound file for the login sound in Linux Mint 13:

The only thing you need to remember is that the new sound files must be in .ogg extension. To convert an .mp3 file to .ogg, you can use ffmpeg. To install ffmpeg in Linux Mint 13, just run the following command:

 sudo apt-get install libav-tools  

After that, to convert an .mp3 file to .ogg, the command will be:

 ffmpeg -i input-file.mp3 output-file.ogg
