I ran audio_cloverALC script and it went well. Internal Speakers work, but when I plug my headphones into the front panel nothing happens. It doesn't show up as an output and there's no sound.
I am running Sierra 10.12.4.

 

[tecsa]

Sorry it started working I don't know how.

 

[toleda]

nothing happens
