OBS, separate audio track but mic is still capturing desktop noise


New Member
I record on MKV and remux it to MP4. I've also split the tracks(2 tracks). When I go into Movie Studios Platinum 17. The 1st audio track has my mic and desktop audio while the 2nd track has just the desktop audio. I don't understand what I'm doing wrong here. Is it because my mic is close to my laptop.
Has somebody else had this problem before, I'd appreciate the help.

Mic: Blue Snowball
Desktop Audio: Speaker Realtek(R) Audio
Laptop: Dell Inspiron 7500 2n1.
