Lenovo X1 Carbon 2015 dead ports

So a month ago I bought a brand new 3rd gen x1 carbon. It was awesome right up until when I wanted to use the headphone jack. No sound. So I run a self-test through the pre-installed Lenovo Solution Center annnnd it tells me everything is fine. hmmmmmmm. I google led me to this.

TL;DR is that some slapdick assembly worker missed connecting the cable that feeds the left USB and audio port. And apparently I’m not the only one to have this problem.

Paid $1500 for an ultrabook, poor QC.
(still an awesome laptop though)
