So here I am customizing the newly installed LMDE (Linux Mint Debian Edition). So here’s how to remove the “beep” sound on your Debian Mint (take from Linux Mint Community Tutorial):
A. Stop the pcspkr module from loading:
- In the Terminal (re)move /etc/modprobe.conf, if present
- In the Terminal create a file /etc/modprobe.d/pcspkr.conf containing: blacklist pcspkr
- In the Terminal type: su
- This gets you a login on the Terminal as root (you’ll need to authenticate).
- In the terminal type: depmod -ae
- Ignore any warnings.
- In the Terminal type: update-initramfs -u
- In the Terminal type: exit
- This puts you back at the Terminal prompt as the original user.
B. Configure Alsamixer:
- In the Terminal type: alsamixer
- Press [F5] to list all audio channels.
- Look for a channel called ‘Beep’. If there isn’t one try selecting a different sound card by pressing [F6].
- Once you have found ‘Beep’, highlight it and lower the volume to the bottom. Then press the [M] key on your keyboard to mute it. ‘MM’ should now have appeared in the square under the volume scale.
- Press [ESC] to exit from Alsamixer.
- In the Terminal save the Alsamixer changes by typing: sudo alsactl store (authenticating if neccessary).
- Reboot the machine. If everything went well there will be no logout/shutdown/restart beeps heard or login screen beeps when the system comes back up
The guide is very straightforward to follow so no problems here. By the way, this one really works! Thanks to Darkness for writing this!
I turned off the opening sound under Cinnamon via System Settings/Sound/Sound Effects. There doesn’t seem to be a closing beep. – Jon
Thanks for the additional info Jon!
