game bar causing weird sounds coming from my mic

It's like it used to record from the mic and from the audio sent to the headset and audio sent to the speakers but now its the mic and only the audio output selected in the sound setting in the system tray on the windows task bar.

Its weird cause the mic works just the buttons don't.

Mic monitoring is the ability to hear yourself through the mic. Many people confuse this with noise canceling. Mic monitoring helps with people that cannot hear themselves while there is gameplay. This sometimes causes people to be extra loud and start
yelling when they can't hear themselves from the mic. Noise canceling mics will normally have 2 mics, one on the inside for you talk through and the other on the outside to listen for background noise and to "cancel" that sound that comes from the second mic.
The options will be in the sound section when you hit your menu, this option is not there if you do not have a headset plugged into your controller.

With me All stereo type headsets failed to work, only input sound but no mic. With the basic chat set the mic works but the gamesound comes from my tv

Both the HDMI Audio and Optical Audio is set to "Stereo Uncompressed" in my XBOX Settings Menu.

Yes, I have tried connecting the Sound Bar to my TV. I don't have an Optical Input on my TV, so I used the Red / White RCA cables. The Sound Bar does not work from the TV - because it is not on the same HDMI input.

(I have 7 inputs on my TV: XBOX One is on Input 7, and my cable box is on Input 8. The RCA Inputs are on Input 4.) When I connect the Red / White RCA cables to my cable box though, the Sound Bar works perfectly.

This is what is confusing. HDMI sound and RCA sound is coming fine from the cable box. But, only HDMI sound is coming from the XBOX One. The Sound Bar is silent.
