Windows' microphone level-boost has no effect - no difference at any setting, from minimum (0 dB) to maximum (+40 dB) Anyone know why this is or what is the fix please? Details below... Following successful resolution of my previously posted issue in getting the on-board (macbook) microphone to work at all in Windows 10 VM, now I'd like to adjust its boost-level, but that (slider-control, as below) currently has no effect. Any way to fix this (or my expectation) ? In Dialog-Window:[Microphone Properties]... ...in its [Levels] tab... ...the [Microphone] level-control (slider) works as expected (though I wish it was logarithmic not - I assume - linear, because audible level changes too quickly at the top) ...the [Microphone Boost] level-control (slider) has no effect (should it?) I tried varying from its minimum (0 dB) to its maximum (40 dB) I assessed the resulting level via first by the Windows mic-level test and afterwards by the Windows Voice Recorder app ...in its [Advanced] tab, [Exclusive Mode] setting... I tried both un-checking (and [Apply]) and checking (as per its default state) (and [Apply]), then repeating the above tests, but there was no difference - the [Microphone Boost] level-control (slider) still had no effect. I tried it because of advice given in (the final post in) this Microsoft Answers thread. ...
