Inspiron 15 7559 - Hearing back the output volume with headset.
I have an Inspiron 15 7559, and when I'm Gaming and I'm speaking with my friends at the same time, they can completly hear back the whole game, even if I turn down the volume. Plus, the headset I have, including mute button on the wire, and if I switch it to "Mute", they still can hear the game. To be honest, they can hear my whole output volume, like if I'm listening to music with Spotify or with YouTube.. Also the Stereo Mixer is blocked/disabled. Headset: Kotion Each G9000. It's so fustrating that they can hear back everything. I'm puzzled.
to be exact:
my 7559 is equipped with the 4K Touch Display, i7-6700HQ CPU, 8GB DDR3.
Just because I know there are other versions of 15 7559.
