Ok well first of all let's clarify a few things.
1. Do you happen to know if your audio card is integrated on your motherboard, or do you have a separate audio card?
2. I see you have a usb audio device. Are these logitech headphones with a usb connection? If so, do these headphones work properly when plugged in.
Now you can try updating your drivers for your webcam as they are out of date. Get the 32 bit version.Logitech Quickcam E2500 Driver
I would advice uninstalling your current webcam drivers before installing the new one.
Is the webcam working now?
