Bluetooth speakers are connected.
External USB audio devices are recognized.

Sometimes the issue is simply caused by a loose connection or incorrect output device.

Step 2: Verify System Volume

Many users accidentally mute Linux Mint without realizing it.
Open :
Menu → Sound
Check that :

Master volume is above 50%.
Audio isn't muted.
Application volume sliders are active.

You can also use : alsamixer
If channels display MM, they are muted.
Press : M
to unmute them.
Increase volume using the arrow keys.

Step 3: Select the Correct Output Device

Linux Mint may automatically switch to HDMI or another disconnected audio device.
Navigate to :
Menu
→ Sound
→ Output
Choose the correct device :

Internal Speakers
Analog Output
Headphones
USB Audio
Bluetooth Device

Test the sound again.

Step 4: Restart the Audio Service

Sometimes the audio service crashes after updates or waking from sleep.
Restart PulseAudio :
pulseaudio -k
pulseaudio --start
For PipeWire systems :
systemctl --user restart pipewire
systemctl --user restart wireplumber
Play a test sound afterward.

Step 5: Test Audio Output

Run : speaker-test -c 2 or speaker-test -D default
You should hear alternating sound from the left and right speakers.
If nothing plays, continue with the following steps.

Step 6: Check Detected Audio Hardware

List recognized sound devices :
aplay -l
Example output :
card 0: PCH
device 0: ALC897 Analog
If no sound cards appear, Linux Mint isn't detecting your audio hardware.
Also check : lspci | grep Audio or lsusb
for USB audio devices.

Step 7: Inspect Audio Drivers

Determine which audio driver is currently loaded.
Run :
lsmod | grep snd
Common drivers include :

snd_hda_intel
snd_usb_audio
snd_sof_pci
snd_hda_codec_realtek

If no audio modules appear, reload them :
sudo modprobe snd_hda_intel

Step 8: Reload ALSA

Restart the ALSA subsystem : sudo alsa force-reload
If unavailable : sudo systemctl restart alsa-restore
Then reboot your computer.

Step 9: Reset PulseAudio Configuration

Corrupted PulseAudio settings are a common cause of sound failures.
Delete existing configuration :
rm -r ~/.config/pulse
rm -r ~/.pulse
Restart PulseAudio :
pulseaudio -k
pulseaudio --start
Linux Mint automatically creates fresh configuration files.

Step 10: Reset PipeWire Configuration

Newer Linux Mint releases increasingly use PipeWire.
Reset configuration :
mv ~/.config/pipewire ~/.config/pipewire.backup
Restart :
systemctl --user restart pipewire

Step 11: Install Missing Audio Packages

Update package lists : sudo apt update
Install audio components :
sudo apt install alsa-utils pulseaudio pavucontrol
If using PipeWire :
sudo apt install pipewire pipewire-pulse wireplumber
Restart the system afterward.

Step 12: Use PulseAudio Volume Control

Install : sudo apt install pavucontrol
Launch : pavucontrol
Check :

Output Devices
Configuration
Playback
Input Devices

Often applications are assigned to the wrong output.

Step 13: Check HDMI Audio Priority

HDMI frequently becomes the default audio output.
If using laptop speakers :
Open :
Sound Settings
→ Output
Change from : HDMI to Built-in Audio
This resolves many "no sound" cases.

Step 14: Verify Bluetooth Audio

Reconnect Bluetooth devices.
Restart Bluetooth : sudo systemctl restart bluetooth
Reconnect the headset.
Check that the correct Bluetooth profile is selected.
Sometimes switching from Hands-Free (HFP) to High Fidelity Playback (A2DP) restores normal audio quality.

Step 15: Update the System

Outdated packages sometimes contain audio bugs.
Update everything :
sudo apt update
sudo apt upgrade
Reboot after installation.
Kernel updates frequently include improved hardware compatibility.

Step 16: Try Another Kernel

Occasionally a newer kernel introduces driver regressions.
Open :
Update Manager
→ View
→ Linux Kernels
Install :

an earlier stable kernel
or a newer LTS kernel

Reboot and test audio again.

Step 17: Examine System Logs

Inspect kernel messages :
dmesg | grep snd
or
journalctl -b | grep audio
Look for :

firmware errors
codec failures
driver loading problems
hardware initialization issues

These logs often identify the exact source of the problem.

Step 18: Check BIOS Audio Settings

Some systems disable onboard audio within BIOS or UEFI.
Enter BIOS setup and verify :

HD Audio enabled
Onboard Audio enabled
Legacy Audio enabled (if available)

Save settings and restart Linux Mint.

Step 19: Test with a Live USB

Boot Linux Mint from a Live USB without installing it.
If audio works normally in the live session :

hardware is functioning correctly
the installed system configuration is likely corrupted

If audio still fails, the issue may involve firmware or hardware.

Step 20: Reinstall Audio Components

As a final software solution, reinstall the main audio packages.
sudo apt install --reinstall pulseaudio alsa-base alsa-utils
Or for PipeWire systems :
sudo apt install --reinstall pipewire pipewire-pulse wireplumber
Restart the computer after reinstalling.
