External microphone volume settings back to 100% after few seconds

Hi. I have issue that my microphone volume settings revert to 100% every few minutes/seconds after movie it into 150%. I don't know if it helps but I use my headset when I plug my mic.
I use pavucontrol to manage my volume  and I use external sound card Generic_Realtek_Audio_USB.
This is output from:

 arecord -l 

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC298 Analog [ALC298 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: USB [Realtek Audio USB], device 0: USB Audio [USB Audio]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

And I past result from:
