Snapcast VS Volumio

You could connect airplay to snapcast[0] then use an embedded snapcast player, like mine[1], I do this on an ESP32 with 320KiB of SRAM

I tried shairport some time ago, but settled on https://github.com/badaix/snapcast and have a really great and reliable open-source multi-room setup

I’ve had success with Snapcast when looking into this previously https://github.com/badaix/snapcast

Works perfectly on pis scattered around the house.

Snapcast: The cheapest and most modular option is deploying small form factor linux clients (raspberry pis, or any host all) with an audio interface (3.5mm, RCA, or otherwise), and connect the audio output interface to your choice of speaker. Snapcast is the open-source multi-room brains. It works well in my experience, but it is tricky to get setup properly to start with. Spotify Connect support is possible so you can launch your Spotify listening session from the Spotify app. Snapcast also integrates into Home Assistant for ease of adding/removing clients from the active listening sessions (yes, plural. You can have multiple listening sessions from multiple audio input sources at once).

- snapcast - this server/client software will broadcast synchronized audio from any source to any snapcast client. The server and clients can all run on the same computer. Individual clients are assigned to their own usb soundcard. Source and volume for each client is controlled through the webpage and/or homeassistant.

I have a music library on my home server that I use mopidy to play via the iris plugin integrated into my home assistant UI. It plays over Snapcast which streams over the network to multiple devices in the home with independent volume control. I can fire up the Snapcast client in my phone to get it going there as well, which does work over vpn if I'm away, though I generally just fire up the files from my phones SD card for out-of-home listening. I recently started using whipper on Linux to extract audio from craigslist cds.

You want SnapCast. You'd run snapserver on your Linux box and snapclient on your Pi's. Snapserver has support for Airplay (via shairport-sync) and Spotify (via librespot). I recommend using MPD for your music library, as I don't think PlexAmp can output audio in a way that's useful for snapserver.

Instead of splitting audio from the jack output you can create a Little network with a router and have more rpi streaming music over It using snapcastsnapcast .

If you're into the idea of an open-source client/server architecture, then there's Snapcast. If you have a few Raspberry Pis (one per output source) or any other box that can run Linux and has an audio out interface, then this is cheap and easy with an active Home Assistant integration too.

Possibly volumio OS - found at volumio.org

You can find some ways to kind of hack something together. It's not as convenient as a ready-made consumer product, but you can get a Raspberry Pi and install something like Volumio on it. (I haven't personally used Volumio, so that's just an example more than a recommendation, although it's probably good.)

Haven't tried it myself but Volumio looks like a nice option.

For anyone else who wants to do this, just set up the absolutely amazing Volumio on your RPi or any other computer.

The web app is great for use in your house, the Spotify plugin is first class - it's supported as a target in your Spotify app, or you can browse straight from the webapp, which means even a guest on your wifi can easily pop on and help pick the music.

If you're using Spotify, a Raspberry Pi 4 running Volumio (https://volumio.org/) is a sub-$100 setup (the Pi is cheap but you'll want a case and whanot) that works great. Volumio will turn it to a Spotify Connect endpoint that you can control via your phone/computer through the normal Spotify app. Use the Pi's USB out directly into the Bifrost (don't need to bother with any of the hats) and you're all set!

What I ended up doing is running Volumio on a raspberry pi hooked up to an AudioQuest Dragonfly USB DAC, which in turn outputs to one of the analogue inputs on my main amp. It's not as slick as a native Plex client, but it works well enough and (thanks to that DAC) sounds really good.

Buy a music streamer. Like iFi Audio Zen Stream, Bluesound. Or Raspberry PI running Volumio (https://volumio.org/). Or maybe a VM running Volumio, pass the USB to it?

If you just want to play music, look into Kodi-based distros like LibreElec or OSMC, or audio-only distros like Volumio. Failing that, antiX or Q4OS Trinity.
