Oops. I guess I should have read your post better. I use different inputs for my audio. If that's not an option the only other thing I can think of would be an A/B switch to swap the feeds to the stereo. I've seen remote ones that I'm sure the 880 could switch. I have one from radio shack that I used to use. It does composite audio and s-vid. It's an added device to the setup but it might do what you need.
