You're not SOL. You need to go into the setup menu and let the receiver know that out of all the options there are for audio input that you'd like it to match the component #1 or #2 (or whichever one you have the Wii connected to) with a certain audio analog input. Some receivers have red & white RCA jacks next to the component input jacks - some do not and must be set up in the setup menu.
If your receiver has an auto scan function - and I don't know if it does or not - turn it on. It will scan all available audio inputs and select the one that has a signal incoming.
And make sure you have the analog out from the Wii connected to CD - DVD - Aux - something. No audio flows through the video component cables.
