I have a problem with the Win 10 and Audacity combination on mij laptop.
It seems te be a soundcard problem, but I cannot seem to fix it.
When I record anything the input indicators go as it should be.
However, very low level signals are not recorded bij Audacity.
It seems there is some sort of “noise cancelling” with a threshold active.
There are some adjustments to make in the internal soundcard like “voice activated recording”, in my case this is switched off.
It must be a Windows 10 issue, while on the same laptop with Win 8.1 everything worked perfectly.
On my desktop with WIN 8.1 I upgraded this morning to Audacity 2.2.1 and it is still working flawless, so it is not an Audacity issue.
