The headphone jack is not working on my laptop, I can see an option called "Headphone" on alsamixer I pull the volume to maximum and plug the speaker in and there is no sound output from headphone jack, how to debug?

4nn13,
I may be a model problem.
The specification for Intels High Definition Audio Controller leaves a lot to implementers.
Read /usr/src//linux/Documentation/sound/hd-audio/models.rst
Find your codec and work your way through the model= parameters.
You pass that to snd_hda_intel when it loads. How you do that depends on how snd_hda_intel is built.
| Code: | | grep -i codec: -R /proc/asound/ |
will list your codecs.
