Hi

i have two laptops Dell inspiron 15 7000 gaming. Both have the same issue.

I need to send one audio to left speaker and another audio to right speaker, but i have both audio signals in both speakers. 

For example: I plugin 3,5 jack to laptop and plugin one cinch to external speakers (second cinch is unpluged). I play sound from https://www.youtube.com/watch?v=hTvJoYnpeRQ. I´m supposed to hear only "left channel" or "right channel" (depends on which channel is plugged), but i can hear "left channel" and "right channel".

When i watch a movie or play a game its hard to recognize, but i need fix this for my app.

When i do the same with Dell inspiron 13 500 series or deskop computer Lenovo, its working well (i can hear only "left channel")

Is there something i need to disable? 

Thanks for every advice.
