Try restarting the PulseAudio sound server by running the following command in the terminal. This can help fix sound issues caused by the sound server.

pulseaudio -k

Ensure your speakers or headphones are correctly connected to your system’s audio port. If using Bluetooth audio, ensure the device is properly paired and connected. If you’re using a system with proprietary audio hardware, double-check that you have installed the necessary drivers. Use the “Additional Drivers” app to install any available audio drivers.

Clear the audio cache by running the following command in the Linux Mint terminal. It helps fix issues caused by corrupted audio files.

rm -rf ~/.config/pulse; pulseaudio -k

Try reinstalling audio-related packages. It resolves almost all problems caused by missing or corrupted audio packages. This can be done by running the following command:

sudo apt-get install --reinstall alsa-base pulseaudio

6. Updating issues

Linux Mint users encounter updating issues from time to time. Software conflicts, outdated packages, or problems with the update process can cause these. Fortunately, there are several troubleshooting steps that you can take in such scenarios.

The first thing you should do when encountering update-related issues is to ensure that your internet connection is stable and working correctly. A weak or unstable connection can cause update failures or result in packages being corrupted during the update process. If you’re having trouble, try resetting your router or contacting your internet service provider.

Sometimes, packages can become broken or corrupted during the update process, leading to issues when updating your system. Open the terminal and run the following command to check for broken packages. It scans your system for any broken packages and provides a list of them if any are found.

sudo apt-get check

To fix broken packages, you can run the following command.

sudo apt-get install -f

If you’re having trouble updating your system, your package sources may be outdated. Open the terminal to update your package sources and run the following command. This ensures that you’re downloading the latest updates for your system.

sudo apt-get update

In some cases, conflicting packages can prevent updates from being installed on your system. To instantly remove conflicting packages, run the following command:

sudo apt-get remove appstream

Replace appstream with the name of the package that’s causing the conflict. You can then attempt to update your system once again. Linux Mint has a built-in update manager that makes installing updates and troubleshooting issues quickly. To open the update manager, click on the menu icon in the taskbar and select “Update Manager”. From there, install available updates and view any errors or warnings preventing proper installation.

7. Display issues

Use the Display Settings tool or the “xrandr” command to check if the correct display resolution and refresh rate are already selected. Make sure that you have the latest graphics drivers installed. Go to the “Additional Drivers” app to check for and install any available updates.

Try disabling the compositor by going to System Settings > Window Tiling and turning off the “Enable window tiling and snapping” option. This can help fix screen tearing issues. Next, adjust graphics settings by going to System Settings > Graphics and changing the settings to use “tear-free rendering.”

Edit the Xorg configuration file by running the following command. Doing so will fix issues caused by missing display packages for specific applications.
