I'm wondering if it's not working because another device is taking control of it.
Something you can try is to restart your computer, and then when it comes back up delete the source you have now and create it again this time as a global source.
One more thing you can try is to create another virtual audio cable. This should theoretically work if iTunes is the one interfering with obs. You can open the control panel for vac and then add another line. From here, open the mme audio repeater for vac and set input to line 1 and output to line 2. Then, add the direct show audio source back in and set it to line 2.
If all else fails, you can go with the virtual audio cable approach and send both your mic input and your iTunes to virtual audio cable 1 and then in your audio settings set your mic to virtual audio cable 1.
Let me know if any of these work out for you (:
