That Pi in your drawer?
It's already a €400 streamer.
Flash an SD card. Your Pi wakes up as a full streamer, ready for Home Assistant.
Every protocol. Every source. Every room. Free.
Works like any commercial speaker. Control power and pairing from the UI, PWA or Home Assistant.
Stream from any Apple device directly to your Pi with zero configuration.
Snapcast integration for perfectly synchronized audio across every room.
Full UPnP renderer and server via upmpdcli — works with every media client.
Insert a disc or USB drive — playback starts automatically with full metadata and cover art via GnuDB and MusicBrainz.
PulseAudio TCP sink — any Linux machine running PulseAudio or PipeWire streams to the Pi natively, no extra client needed.
Not just a media player card. Services, outputs, Bluetooth, power: complete odio stack as native HA entities.
Install the web app on any device for a native-feeling control experience.
Your existing subscriptions, on your Pi. No extra cost.
Your Pi appears as a Spotify Connect device. Control from any Spotify client.
Full catalog via upmpdcli. Hi-res included.
Full catalog via via upmpdcli. MQA and lossless.
An open-source audio streamer for Raspberry Pi. Not a locked appliance: a platform to build on top of.
Every protocol, every source, every room. Free, self-hosted, no account, no cloud.
Your Pi becomes an AirPlay receiver, a Spotify Connect device, a Bluetooth speaker you can turn on from a Home Assistant automation. Try finding a commercial speaker that lets you do that.
Built for makers first. Every node exposes a REST API. Every service, every player, every audio client is an entity you can observe, control, and automate. Wire Piper and Whisper to MPD and your Pi becomes a voice-controlled player. Set up parental controls your kid will have to learn to bypass. Shut down the workstation you forgot running from your phone, halfway to the store. The surface is there. What you build on it is yours.
Custom clients, custom automations, integrations no one has thought of yet. The API is the product. Your setup, your rules.

Two paths. Same destination.
Use Raspberry Pi Imager with a custom repository URL. Configure hostname, SSH & WiFi, then flash.
Debian 13 (trixie) and Ubuntu compatible. The installer handles all dependencies and services.
Tip: set up DAC and overclocking (armhf) in /boot/firmware/config.txt beforehand to save a reboot.

In 2016, I bought a €35 Raspberry Pi B+, a HiFiBerry DAC, and put them in a wooden box. I wanted a complete streamer, open to any source, any client. A dumb amp, and between it and the rest of the world, a free machine where no one else held the lease. No vendor who could decide, one day, that it had become obsolete.
Over the years I tried everything: Volumio, RuneAudio, Mopidy, Pi MusicBox. Three times Volumio. Each time the same story: Locked appliances, Bluetooth that barely worked, audio cracks, half-broken setups. Never quite right. Never quite mine.
During the first COVID lockdown, I finally stopped tweaking other people’s system and built what I actually wanted. The Pi B+ is still running. It’s 2026.
Hardware doesn’t become obsolete. Someone decides it is.
In 2022, Sonos pushed a software update that permanently degraded its older speakers, hardware that worked perfectly the day before. Not a technical necessity. A choice. Pay for new hardware or accept a worse product you already bought.
Two years later, a mandatory app rewrite silently removed dozens of features overnight. Same hardware. Same network. Alarms gone. Local library, gone. The product you bought runs on software you don’t control, updated on a schedule you didn’t choose.
Every mandatory account to stream audio inside your own home is a lock you didn’t choose. Every €60/year subscription for Bluetooth, a 25-year-old protocol, is a rent on something you already own. Every dropped Pi model is a device that becomes e-waste not because it stopped working, but because a roadmap said so.
Every streaming session has become data, to be collected, profiled, monetized. It’s not a side effect, it’s their model. For the entire lifetime of your device.
odio is a refusal. Not of progress, but of the model where someone else holds the keys to what you own and use that to steal and sell your data. A DAC plugged into a thirty-year-old amp, a Pi bought last decade, still running in 2026 because every layer is replaceable, every protocol is open, and nothing in the stack depends on a company staying alive or benevolent. That same hardware now speaks AirPlay, Spotify Connect, Tidal, and talks to Home Assistant through an API that didn’t exist two months ago. Free software is not just a philosophy here. It is the engineering condition for durability and sustainable hardware, and the only foundation on which you can keep building without starting over.
Keeping a 10+ yo board alive in 2026 is not nostalgia. The most sustainable device is the one already manufactured.
odio exists because the tools it depends on — MPD, PulseAudio, Shairport Sync, Snapcast, upmpdcli — were built by people who chose openness. The same deal applies here.
Every line is readable. Every binary is reproducible. Bug reports, patches, and opinionated configuration choices are all welcome.
