Audio Hardware issue - Appropriate selection not there?

This morning when I opened Audition after using it last night with no issues whatsoever, I entered the Audio Hardware settings to change my input device from my RopeCaster Pro over to Speakers/Headphones so I can record some audio in to Audition from my web browser.  For the first time ever, I clicked the dropdown menu and the option that has always been there (Headphones/Speakers - Realtek High Definition Audio) is not there.  The only options I can select are my Rodecaster, my Webcam, or my USB Mixer (USB Audio Codec).  Before this is suggested, please know that I have tried both of the other Device Classes (ASIO and WASAPI) and neither of them worked either.  I haven't needed to switch out from MME class ever before.  PLEASE HELP!  I have a Podcast scheduled tonight and this will for sure ruin it if I don't get it fixed!  THANK YOU!!!!
