You seem to have your digital output selected as the desktop audio device, is that the correct device?
For the Microphone you seem to have a kraken headset mic selected. You might want to switch the desktop audio device to the kraken as well. If you have problems getting the kraken to work:
"Problems getting the Razer Kraken working? Use the 64-bit version of OBS - it's installed automatically, look in your Start Menu. If you're stuck on a 32-bit system, disable the Kraken launcher in msconfig's Startup tab (press WinKey+R, type "msconfig" in the box and press Enter) and reboot."
