If sound themes are disabled in Gnome Volume Control, it may be due to a few different reasons:
- Sound theme is not installed: Gnome Volume Control requires a sound theme to be installed in order to play sounds. If the sound theme is not installed, the option to enable sound themes may be disabled. To install a sound theme, you can use the Gnome Tweaks tool or run the following command:
sudo apt-get install gnome-sounds
- Sound server is not running: Gnome Volume Control requires a sound server to be running in order to play sounds. If the sound server is not running, the option to enable sound themes may be disabled. To start the sound server, you can run the following command:
pulseaudio --start
- Permission issue: Gnome Volume Control may not have the necessary permissions to play sounds. If the option to enable sound themes is disabled, you may need to check your user account permissions. You can run the following command to see if your account has the necessary permissions:
groups
This will display the groups that your account belongs to. If your account does not belong to the “audio” group, you can add it by running the following command:
sudo adduser <username> audio
These are some of the most common reasons why sound themes may be disabled in Gnome Volume Control. If these steps do not resolve the issue, you may need to consult the documentation or forums for your specific distribution for further guidance.
