Live event - Producer, Organizer and Presenter - Can't hear/Monitor output

Hi,

I am looking to use "Live event" to record presentations for our department. The aim is to use 1 laptop/camera/audio setup to record and stream.

I use an Elgato Camlink to convert the A/V source to USB, and when using headphones on the Camera itself, and when Recording on the camera itself, I can monitor/hear no problems.

... When I use my headphones on the laptop, I select Camlink as Video, and as Audio, and I see the audio bars rise & fall. I cannot, however, hear what is incoming, therefore can't monitor the recording.

I have tried this on 3 different computers..... does anyone have any clues as to why i can't monitor the output?

Thanks.....
