recording iTunes etc into Cubase without audio interface???

Hi Jaslan (or anyone else if you see this before the J man) -

I have a laptop that I’d like to have play Pandora into an analogue-only home receiver (without wireless capabilities).

Where is this “stereo mix” for me to enable that you speak of (“hidden”?)?

And could I route it out my laptop’s stereo headphone output into a the receiver with the right connections? Would I need to use my preamp?

Thanks much -
