The Chromecast, like your other devices attached to your TV, push the sound the the TV and the TV decides where it wants to play the sound. Most TVs let you set that on an input port basis. That would explain why it works for something like your Cable box on Port 1 but not your Chromecast device on Port 2. You need to tell your TV to push the sound from Port 2 to your stereo just like it's set to pus the sound from Port 1.

We haven't heard back from neels, and it's been a few days, so I'm locking the thread. As always, feel free to make a new thread if you have any more questions or concerns.
