I just want the basics …

Hi.

I’m Linux-savvy and this is not so difficult, yet it seems to be.

Here is what I have:

Synology with a known shared path to my music (//hostname/MyMusic)
HiFiBerry assembled and working (I had already tried MusicBox and RuneAudio successfully)

Here is what I want:

Max2Play to catalogue my entire folder’s contents of MP3s for playing
Web page w/o login to choose and play songs, playlists, artists, etc.
Web page W/ login to manage the previous two „wants“ mentioned

Here is what I’d like:

Max2Play to been seen by my iPhone as comparable item in the list of existing Chromecast devices on my network
Max2Play to be groupable with my existing Chromecast devices for multi-room play
Max2Play to SEE my Chromecast devices for output*
* output to be BOTH the RCA physical output and the Chromecast network output

Leaving the „Likes“ aside, I’m finding it difficult to just get this up and working simply.
And, the videos are too long to get to the meat of instructions I simply need.

Thanks in advance for anyone who has been down this road and can respond with the steps to succeed.

Alan
