Windows automatic mic level

Post by thierry »

Hi

When using the XP-VF3500 dev board, I can see that windows microphone level is auto adjusting its value, whether I have AGC enabled on my board or not.
I wonder if this is due to some HID parameter sent to windows. This is not happening with other USB microphone I have.
Is there a way do disable this behavior ?

Thanks

Found it was not due to the mic it was due to a software that was trying to do AGC with windows
