Hi all, thank you for the help!
A couple answers and updates.
1. Tidal works great in the app if you're simply selecting a room and playing music. If you try and get smart or put it into scenes, it doesn't work. You can't select anything in when then and I'm told its a bug they are working on. Though it is still not working and it has been over a year. I did find that Spotify is much more reliable and now have this in my Alexa routines working great. Tidal never worked in this manner.
2. My Roku is at the rack and run through a receiver
3. I had Cat6 run with the build. We used that initially and it was horribly buggy. We replaced the baluns with upgraded ones and still weren't able to get things working. Now I have a 75ft HDMI cable run (not optimal) and it works much better. The issue is delay - when we start new videos or turn the system on you get sound long before picture. Sometimes the TV doesn't even recognize the input and doesn't switch over at all so you have to completely restart everything and try again.
4. The way we got Alexa voice working was to place an Alexa at the rack and set up voice scenes. It works ok, but yes, you need to be very clear about how you want your commands set up. Check the attachments. Of course, the issue is that I need the dealer to work on this stuff for me. It's nice though that after you turn on a room audio, you can speak to Alexa fairly normally for song selection and/or volume. It can be a little goofy if you don't turn off the room audio audibly before other routines run.
Overall, I'm not too happy and think there are probably much easier solutions through Amazon, Google, Apple etc. This is just very expensive and very closed.
