Am I imagining this? Should the setting I've shown remain checked? Or, as I have to do in MEP 2016 and 2017 does it have to be re-enabled for every recording?
I don't recall ever even thinking about this until today. But as the function itself does remain enabled, maybe I've just never noticed!
FWIW:
All looks OK in Device Manager > Sounds.
MEP and PC restarts haven't fixed it.
The mic, an AKG Perception 120 USB, which has been working fine for years, doesn't appear implicated, because switching to my Logitech webcam mic made no difference.
It's only one extra click but - if it is indeed a flaw - I'd like to sort it! Any ideas please?
