alsa-project/alsa-ucm-conf issue #298 was opened from Noted-Jrelvas:

First of all, apologies for the verbose title.

I've ran into a very interesting issue with my Thinkpad X1 extreme gen 5's audio. For whatever reason, the headphone jack's sound output is very quiet unless I raise the speaker channel's volume past a certain threshold.

The headphone jack sounds very quiet... 

...but raising the speaker channel's volume fixes the issue: 

I suggest automatically setting the speaker channel's volume to 100% when the headphones are plugged in and restoring it to its original volume once they're plugged out.

Here's the output given by `alsa-info.sh`: http://alsa-project.org/db/?f=21904435b29e0eb23d2d0b30bbabe15734df7ad7
