ok. so i build a new computer not long ago and when i plugged my blue yeti (a microphone) into it my headphones stopped working. i got them to work by changing the realtek settings on the speaker configuration from stereo to 7.1 speakers, however only some of the sound works and others dont. for example look at this link http://prntscr.com/817pb1 the two ones that i circled i can hear out of but all the others i cant hear any sound out of when i test it. help plz
