This is actually a bit weird problem. Whenever I plug in my earphones on my PC, I hear only the background sound. But if I press and hold the receiver button on my earphones, I hear both vocal and background sound. But when I plug the earphones halfway through, I hear both vocal and background sound but in mono, no stereo. This problem is killing me... I need a solution! I didn't have the problem before... * I tried cleaning the port on my laptop * I tried reinstalling my sound drivers

This is typically used for VOIP calls I would suspect (where it automatically reduces the volume so you can hear the other person).

First off, your jack plug has 2 black lines. This indicates stereo. If you only press it in half way through, only one of these makes a contact (hence the mono sound).

Open Control Panel -> Sound

Click on the Communications tab

Select `Do Nothing`

I tried it before, but didn't work... :( – MRahman Oct 1 '13 at 5:27
Does this issue only occur with these headphones? – Dave Oct 1 '13 at 7:03
No, any type of phone headphones... – MRahman Oct 1 '13 at 11:13
So, what happens if you roll the drivers back, or even a System Restore to before the issue? – Dave Oct 1 '13 at 11:21
I tried everything, buddy.. I mean everything you mentioned... – MRahman Oct 2 '13 at 11:10
