I have a Asus notebook X450L running windows 8.1. I also have Sennheiser pc hd 350 headset that has a mic and a mic plugin and a speakers plugin. the laptop only has one audio jack. its a green one so I'm assuming its for speakers and when I plug my mic plugin into the jack and I hear nothing and the mic doesn't work. I put the speakers plugin into the jack and it I used to be able to hear things from the headset and use the internal mic on the laptop but all of a sudden when I would plug in the speakers the internal mic wouldn't work anymore. but when I removed the speaker plugin I could hear the sound from the laptops internal speakers and could talk from the internal mic. but mind you it sucked and I had a $200 headset laying around doing nothing. PLease help me D: I hope I don't have to spend money. and if I do I hope it isn't too much cuz I'm saving but please help me out here guys. Thanks in advance! also. I didn't know where to put this so I put it here :3
