Blackshark v2 pro sidetone

Just received my blackshark v2 pro. I have sidetone turned up to 100 in synapse.

The only way you can hear yourself is if the volume knob on the headset is between 75-100%. I shouldn't have to do that.

This should be a simple software fix, there is nothing wrong with the hardware as far as I can tell.

Sidetone surely should be implemented as a percentage relative the volume the knob is set to. If I set the sidetone volume to 100 and the knob is at 50, I should be hearing myself as loud as any other sources (games, music) being played at 100% the time. Instead, sidetone seems to be implemented as a fixed value relative to the maximum output of the headset.
