All sounds from PC can be heard by the other side when using microphone

[Daniel-V]

Hey everyone, i have problem here and i wan't sure where to ask. I own HyperX Cloud Dron, and when it's connected to PC this occurs - Sound from PC (Spotify music, or voice) can be heard by the other side. This would be normal if my mic sensitivity would be too big, but there can be complete silence in the room, but music playing on PC can be still heard by other side. Any ideas? I'd appreciate some solution, because it's very nosy for friends to hear their echo every call.

Probably it's not problem of Stereo Mix in Windows because it's enabled whole time.

My spec:
Windows 10 Pro x64
Asus GTX 960 2Gb
AMD Athlon II X4 641
ASUS F1A75-M LE
EVOLVEO Pulse 550W
KINGSTON 2x4Gb DDR3 CL9
WD Green 1tb/Seagate Barracuda 3tb/ADATA SP900 128Gb/WD My Passport 1tb

I don't suppose you have VAC running?

The sound card/chip doesn't differentiate the audio and smashes them all together when you transmit. This is an old problem and the only way to get it fixed is to use a different brand of sound card/chip.

Is there a specific driver for the new headphones?

Nope, there is no driver for my headset.
