Blank audio recording?

[G-string]

At that time Skype was turned on so that I could chat with interpreters next door and he was a suspect as well, however after shutting it down the problem still remained, so I believe he’s not the culprit. TBH I don’t really remember what I set as a mic/headphones in Skype as it was a last-minute install.

Yes, sleeps are turned off

Other than that, this PC has been dedicated to the recording, so no other programs are running.

Did you try a reboot after closing Skype ?
