Quick fixes to try first:
Re-pair headphones:
Re-pair headphones:
3.5mm audio jack:

USB headphones:

If your headset has a single plug for both audio and microphone, but your PC has separate jacks, you'll need a splitter adapter:

Open Device Manager:
Look for issues:
If update doesn't work, try: Right-click → Uninstall device, then restart Windows.
macOS handles audio drivers automatically. Try these steps:
Check audio system status:
# Check PulseAudio status pulseaudio --check pulseaudio -k && pulseaudio --start # List audio devices aplay -l # Reinstall ALSA/PulseAudio sudo apt install --reinstall alsa-base pulseaudio
Common signs of damage:
The "wiggle test"
While playing audio, gently wiggle the cable near the plug and near each earcup. If sound cuts out, you've found the damage location.
Cable damage near the plug is the most common failure point. For expensive headphones, consider getting the cable replaced professionally.
Run the troubleshooter:
Reset audio settings:
Reset Core Audio:
Open Terminal and run:
sudo killall coreaudiod
This restarts the audio system. It will re-initialize automatically.
Create a new user account:
If audio works in a new user account but not your main one, the issue is with your user preferences, not the system.
If none of these solutions helped, try testing your headphones on a different device (phone, tablet, another computer). If they don't work there either, the headphones themselves may be faulty.
