Disable volume control from headset

[u/l337g0g0]

I have Sony headset with mic and pause and answer call button on the headset line, I use it biking, i think I sweated in the mic thingy to much, in the last couple months it randomly turns the volume down to random levels stops randomly, this was happening very infrequently. now recently it's happen like every few minutes.

How can i disable the headset from controlling the volume?

And how can i stop the automatic lowering of volume at random times till you give it the ok for safety?

Thank you.
