Generally, if the microphone icon under the webcam is on, audio will be recorded. If you don't want more audio input, just toggle that mic off.
But if something is armed (red dot next to it) and you're not seeing a recording, that sounds like a bug. If this persists, is it possible to send us a screen video of what is happening?
It is the second situation where the things are armed but it doesn't record. While recroding it moves to suit what is going on like it is recording but then the only recroding once I press stop is audio and everythign else is deleted. I will be recording more today and will see how it goes. Both a game will be playing at the same time and screen capture will be working on the game though so I won't also be able to screencapture what CA is doings as it will probably start to get a little demanding with so much going on. If I have the same issue though, afterwards I will try to record it playing up. What is unusual though is that sometimes it plays up and other times it doesn't, and afaik I'm not doing anything differently.
This video here: CP The Beginning - Skyrim #1 (Carrie Plays) - YouTube had these issues. It seemed like it would record everything except for the draggers (which I deliberately did separately) but only recorded the audio so I had to watch the lets play afterwards and look at what I would have assumed I would have looked at etc and it greatly increased the amount of time recording took, unfortunately.
I'll let you know how this next recording goes.
Yeah - that's definitely a bug then - I've never seen something like this before. Does this only happen when doing the intensive game + CH setup, or also when you're just using CH by itself?
It has done it both while combining with the game and on its own. The recording I did yesterday though worked fine. I'll bring it up again if it happens again but it all appears to have gone smoothly this time around.
If you want to know anything else about it to try to make it so this bug doesn't occur again though, just ask.
I'm not sure if I can be much help though.
