I was trying to talk to my World of Warcraft guildies, but I couldn't hear anyone even though they were lighting up in Discord. I switched my headset to my mom's computer from mine and it started doing that. I don't know if it would do that for when I put my headset back in my computer or not. My headset was in my computer ever since I got them till today. These are my second pair of gaming headset. I have no idea if my mic on my headset works or not. I did say hi to my guildies, but I couldn't hear anything. This is PC headset I'm talking about too. Both my computer and my mom's have Windows 10. 

And these are a headset that plugs into the computer with 3 plugs (1 green, 1 pink and 1 square).
