I have tested my microphone and all seems ok. In the voice over room, it can pick up my inbuilt microphone and respond at the appropriate level. If I raise my voice the volume level will approach to the red. I am using PD17 on a windows Surface 4 (2017). But whatever I do, the red record button remains grey and will not initiate. Are there any solutions out there? I've followed the tutorial from PD Universary, and I was able to record when I used PD 16, so not sure why I can't do so in this upgrade.
