Of course it's helpful. Thanks. The monoprice linked switcher, Product ID 15263, doesn't have an audio extractor function, unfortunately. I have to find a switcher with audio extraction that has HDCP 2.2 and hope that solves the issue. The other option is downgrading to a non-4K Fire Stick. I am getting worn out returning stuff to Amazon and Monoprice since this is all guess work at this point.
