How to Use Raspberry Pi for Multi-Room Audio Streaming

Multi-room audio is no longer a luxury reserved for high-end smart homes. With a bit of creativity and some DIY tech, you can build a powerful multi-room audio system on a budget. One of the most flexible and affordable tools for this purpose is the Raspberry Pi. When combined with the right software and speaker setups, Raspberry Pi devices can transform your home into a synchronized soundscape.

XTEN-AV is a professional AV design platform that helps plan and document your multi-room audio setup. It allows you to visualize zones, label speaker connections, map wire paths, and keep track of each Raspberry Pi device in your system. When using Raspberry Pi for audio streaming, having a clean and accurate design with XTEN-AV makes the entire process easier to scale and maintain.

In this blog, we will walk you through how to use Raspberry Pi for multi-room audio streaming, covering hardware, software, installation, and configuration. By the end, you will have a clear path to setting up a custom, synchronized home audio system using affordable hardware.

Why Use Raspberry Pi for Multi-Room Audio

Raspberry Pi is a small, affordable, and highly customizable single-board computer. It is ideal for audio streaming because:

• It supports various open-source streaming platforms

• It can connect to both wired and wireless networks

• It supports audio over HDMI, USB DACs, or analog outputs

• It is energy-efficient and compact for room-by-room installation

• It integrates with automation platforms like Home Assistant

Whether you are streaming music from a central server or using services like Spotify or AirPlay, Raspberry Pi can serve as a dedicated endpoint in each room.

Step 1: Plan Your System with XTEN-AV

Before you set up your Raspberry Pi units, start by designing your system using XTEN-AV. Planning your multi-room setup is key to smooth streaming and fewer network issues.

Use XTEN-AV to:

• Define each zone or room

• Assign a Raspberry Pi device to each zone

• Plan wiring for power and audio outputs

• Document speaker types and locations

• Visualize how each device connects to the network or audio controller

With this plan in place, you reduce guesswork and can scale or troubleshoot your system more easily later.

Step 2: Choose the Right Raspberry Pi Model

For audio streaming, the most popular Raspberry Pi models are:

• Raspberry Pi 4 Model B

• Raspberry Pi 3 Model B+

• Raspberry Pi Zero 2 W (for basic needs or compact spaces)

The Pi 4 offers better processing power and supports higher-quality audio, especially when paired with USB DACs. For a clean setup, consider adding HATs (Hardware Attached on Top) like HiFiBerry or Allo DigiOne for improved sound output.

Step 3: Install the Streaming Software

There are several software options that turn a Raspberry Pi into a multi-room audio streaming endpoint. The most popular ones include:

1. Volumio

• Supports high-res audio playback

• Offers web-based control and app

• Can act as a streamer or player

• Supports plugins for Spotify, TIDAL, and more

2. Moode Audio

• Designed for audiophiles

• Customizable with a clean interface

• Supports UPnP, AirPlay, and Spotify Connect

3. BalenaSound

• Ideal for multi-room audio

• Uses Docker to manage devices

• Syncs all Raspberry Pis from a single interface

• Supports Bluetooth, AirPlay, Spotify Connect, and more

Install the software by flashing the image onto a microSD card using a tool like BalenaEtcher. Once installed, connect each Pi to your network.

Step 4: Connect Audio Outputs and Speakers

Each Raspberry Pi needs to be connected to an audio output device. Options include:

• The 3.5mm analog audio jack

• HDMI audio to AV receivers

• USB DACs for better quality

• HiFiBerry HATs for speaker-level outputs

For most users, USB DACs or HATs offer better sound quality than the Pi’s onboard audio. Connect the audio output to active speakers, an amplifier, or an AV receiver in each room.

Document each connection using XTEN-AV so that you can identify and manage your hardware configuration across all zones.

Step 5: Network Configuration

For seamless multi-room playback, all Raspberry Pi units should be connected to the same local network.

Networking tips:

• Use Ethernet where possible for stable connections

• Assign static IP addresses for easier device management

• Use Wi-Fi only for zones where cabling is impractical

• Ensure your router can handle multiple streams

You can also use XTEN-AV to label and organize your network structure and device addresses, making future changes or troubleshooting much easier.

Step 6: Sync and Control Audio Playback

If you are using BalenaSound or Snapcast (another great option), you can stream audio to multiple zones with synchronized playback. The software allows you to:

• Group or ungroup rooms

• Control volume per room

• Choose audio sources like AirPlay, Spotify, or Bluetooth

• Stream the same audio across all zones in sync

Control can be done via mobile app, browser, or third-party integrations like Home Assistant or Node-RED.

Step 7: Add Automation and Voice Control

You can extend the functionality of your Raspberry Pi audio setup by integrating it with home automation platforms. Use Home Assistant to:

• Trigger playback based on routines

• Group audio with lighting or scene changes

• Add voice control via Alexa or Google Assistant

• Monitor device status and control from a central dashboard

Your XTEN-AV design plan will come in handy when configuring automation by helping you understand which rooms and devices are connected.

Step 8: Test and Fine-Tune Your Setup

Once your system is running, do a full walkthrough:

• Test playback in each room

• Check for any audio delay or sync issues

• Adjust speaker volumes

• Confirm source switching and app responsiveness

• Ensure good Wi-Fi or Ethernet signal in all zones

Make any necessary changes and update your XTEN-AV documentation to reflect the final setup.

Conclusion

Using Raspberry Pi for multi-room audio streaming is a powerful and affordable way to bring synchronized sound to your entire home. With the right planning, a bit of tech knowledge, and the support of AV design software like XTEN-AV, you can build a smart, scalable, and reliable audio system that rivals commercial solutions.

By following this guide and documenting your zones, wiring, and configurations with XTEN-AV, you not only streamline the installation process but also make your system easy to maintain and upgrade in the future.
