Sound through speakers works perfectly but though wired headphones, doesn't work. I haven't tried using bluetooth headphoens yet

Any help is appreciated
Thank you

echo "options snd-hda-intel model=laptop" | sudo tee -a /etc/modprobe.d/alsa-base.conf > /dev/null

Reboot to test

Did the required change and rebooted. No changes in the behavior whatsoever. Would like to give out any other required information to get the headphones working.

Thank you


sudo gedit /etc/modprobe.d/alsa-base.conf

Remove the last line, save the new file and close gedit.


Ok, that is just the opposite of what I did earlier. But it did not work. Any other solution is welcome

Thank you

Yes, the line doesn't do anything so should be removed.


echo "options snd-hda-intel position_fix=1" | sudo tee -a /etc/modprobe.d/alsa-base.conf > /dev/null

Reboot to test

Tried. Headphones still not working. Sound still being output through speakers

Ok, remove the line and reboot, then use alsamixer in the terminal

Check volume levels and unmute any muted levels.

I fear that your computer is experiencing the following bug, for which there is no solution yet:


Is there any way in which I can help debug this problem faster? I would really love to help since I have the hardware and can experiment with actions suggested by developers.

Thank you

Can you help with this problem?
