I have a Lenovo Thinkpad T440p. I'm not entirely sure what happened but my sound decided to go out for my headphones. The sound also went out for my speakers but in the process of fixing it, sound now works for speakers but not for my headphones. It's not just that pair, other headphones don't work.

Some output I saw others providing:

Fixed with No sound through headphones while speakers work fine

added

options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=laptop
options snd-hda-intel position_fix=1 enable=yes

to /etc/modprobe.d/alsa-base.conf

and fully shutdown my laptop, removed the battery and booted it back up. Sound now works.

  • This actually does not work for me. Do we really have to remove the battery?
