Apple TV Set Up


I would appreciate some advice on my digital streaming issues. 

My system consist of Vandersteen Treo CT, Mimas with DAC, and the older AppleTV Streamer (model A1469). The AppleTV is connected via Ethernet cables. I digitally stream with Tidal from a MacBook Pro via Wifi. The download/upload speed  for my MacBook is about 230/11 Mbps.

The AppleTV has the latest software update. 

Question 1
Every-time I wish to play, I open my MacBookPro, open the "System Preferences", then "Sound", then choose "Apple TV".
Is there a shorter path or can I set up my MacBook differently?

Question 2
My MacBook sometimes looses connection (AppleTV gets disconnected). I then have to manually connect "AppleTV" again. Why does this happen?

thank you all in advance!

+1 on dumping ATV, its junk, especially the older stuff.
I used it for years and it was a never ending headache.  Take the recommendations here and get a dedicated streaming device.
Had a friend going through same issues with ATV and I finally got him off of it and he is much happier person.
Have you considered Roon to manage your streaming requirements?  Paired with a dedicated streamer it might fit your needs. It can be managed from numerous OS' including iOS, MacOS, Android and Windows.  Roon ready streamers come in all shapes sizes and price points starting with Raspberry Pi options under $100.   The Bluesound suggested above is another viable option.
ATV to me is an amazing steamer. I have the newest model which does require you to buy a splitter box to get optical out and be able to connect a monitor for the visual part. Then use Apple Music or tidal or whatever directly. No computer needed. If you don’t want the visual part, all apple devices control Apple TV’s really well. Even my watch controls the stereo. Very slick if you like the freedom to play whatever strikes your fancy. The UI is very user friendly. If you use the visual part then the remote will do it all. 
Not sure if the Apple TV is capable of this or not. Can you down load Roon to the mac book and Apple TV? Then the atv to an external dac? The Roon app should solve all of this if compatible with the Apple TV.
Good for you Kuna ! obviously there are Apple and competitor experts here to help you. As you know i have the NAIM streamer and also a Node2i. IF you do go with additional investment in a dedicated streamer ( i agree w this recommendation btw ), check input compatibility with your fine Aesthetix DAC. You might be shocked what a different cable costs…

i would loan u my 2i but it’s up North

PS Kuna has a great dog, let’s not get him tangled up in ethernet to the laptop..
