Micro has not input sound(no works) after W10 Update

2020-05-16, 21:15 PM

Hello. I updated Windows 10 from previously versión to 1909 and my external micro does not get input sounds anymore. It is in Plantronics Headset(with its own drivers called Plantronics BlackWire 5220 Series that installed its micro and listening Plantronics drivers as well).

I followed step by step Windows guide to fix this issue(as well as Lenovo) checking if it is muted, checking its volumen, checking privacy settings, reinstalling drivers... but sadly it did not get solved.

Apps like Lenovo Vantage and Microsoft Windows detects my microphone well(When I open Sound config it says Sound is using micro) but as I said the problema it is that micro has not input sound(No Green color in sound config).


Moreover, my audio of platronics headsets Works fine, as well as Internal micro. Sadly quality of this last one is not enough for my daily meetings, so I ask for your help to fix this issue as soon as possible(I do not want buy a new pc when this one is almost new).

I came up with two maybe problems: Micro is with zero volumen somehow(despite in Windows and Lenovo Vantage it says 100), or maybe it could be because DMA is glitched somehow(I asume CPU communicates with DMA and not with drivers, tell me if I am right despite I saw one driver in laptop with name of Interruption I/O that probabily uses this system for other internal drivers...).
