Nothing special, just plugged a Chromecast straight into HDMI1 and the power into a power point. I’ve got a couple of other Chromecast units plugged into TVs so it was simply a matter of using the Google Home app to set it up. If you haven’t used it before, you need to download the app, change your device to connect to the Chromecast wireless signal, change the Chromecast WiFi to your home WiFi, finish the install, connect your device back to your home WiFi and you’re set to go. I did have a little hassle connecting YouTube (couldn’t see the Chromecast to cast to) but a reboot of the Chromecast fixed the issue. I’ve only tried YouTube and Spotify so far but they work fine. I use Spotify to stream as here in my part of the world, not all streaming apps are available and my internet connection is poor.
I’m thinking of using a USB port on my BDP2 to supply power to the Chromecast so it powers down if I turn the system off. That’s the kind of thing I’ve done with the others by using a USB port on the TV that the Chromecast is plugged into.
Early morning here so I haven’t turned the volume up to hear what it sounds like properly, only enough to hear that it works. I’m hoping the BDA3 works it’s usual magic.
