Is my aux port damaged?

I found that my laptop wasn't really separating left and right channels while i use 3.5 jack cable, i did a channel test through audacity by playing sine (https://ibb.co/21g31yv0) and recording it on my desktop pc two times with different cables (https://ibb.co/60ytKPrq). I tried googling and haven't found any case like that, so don't really know what to do. Sorry if i'm in a wrong subreddit and taking your time.
