Build a Raspberry Pi Audio Streamer for Hi-Fi

By HyFa Published · Updated

A dedicated network streamer feeds your DAC or amplifier with music from streaming services, local files, and network shares. Commercial streamers cost $300 to $3,000+. A Raspberry Pi with the right software and an optional DAC HAT achieves the same functionality for $50-$150. Here is how to build one.

Build a Raspberry Pi Audio Streamer for Hi-Fi

What You Need

Hardware

Raspberry Pi 4 Model B (2GB or 4GB) is the recommended board. The 2GB model is sufficient for audio streaming. The 8GB model offers no audio benefit. Budget: $35-$55.

DAC HAT (optional but recommended). The Pi’s built-in audio output is noisy and low-quality. A DAC HAT plugs directly onto the GPIO pins and provides high-quality analog output.

Recommended DAC HATs:

DAC HATChipOutputPrice
HiFiBerry DAC2 ProTI PCM5122RCA, 3.5mm$45
IQaudIO DAC ProTI PCM5242RCA, 3.5mm$40
Allo Boss2TI PCM5242RCA$80

All three support up to 24-bit/192kHz playback, which exceeds the quality ceiling of every streaming service.

If you already have an external USB DAC, skip the HAT and connect the Pi to your DAC via USB. This works well with most USB DACs.

MicroSD card (16GB+). Class 10 or faster. This holds the operating system and software. Music files are stored on a network share or USB drive, not the SD card.

Power supply. The official Raspberry Pi USB-C power supply ($8) provides clean, stable power. Avoid cheap phone chargers, which can introduce noise.

Case. Any Pi 4 case that accommodates a DAC HAT works. The Flirc case ($16) provides passive cooling. Aluminum cases provide shielding.

Ethernet cable (recommended). While the Pi 4 has WiFi, a wired Ethernet connection is more reliable for uninterrupted streaming.

Total Cost

  • Pi 4 + DAC HAT + SD card + case + power supply: $100-$150
  • Pi 4 with external USB DAC (no HAT): $50-$75 plus your existing DAC

Software Options

Volumio

Volumio is the most user-friendly option. The free version provides a web-based interface accessible from any browser on your network. It supports Spotify Connect, Tidal Connect, AirPlay, DLNA/UPnP, and playback from USB drives and network shares.

Installation:

  1. Download the Volumio image from volumio.com
  2. Flash it to the microSD card using Balena Etcher or Raspberry Pi Imager
  3. Insert the SD card into the Pi and power on
  4. Access the web interface at volumio.local from any browser on your network
  5. Configure your DAC output in the settings

The paid Volumio Premium ($54/year) adds Spotify, Tidal, and Qobuz integration, multi-room sync, and parametric EQ.

moOde Audio

moOde Audio is free, open-source, and more configurable than Volumio. It supports the same streaming protocols plus Bluetooth input and output. The interface is functional but less polished than Volumio.

moOde is the better choice for users who want full control over audio settings, including sample rate conversion, buffer sizes, and ALSA configuration.

piCorePlayer / LMS

For Logitech Media Server (Squeezebox) users, piCorePlayer turns the Pi into a Squeezebox-compatible player. LMS is a mature, flexible music server that supports plugins for streaming services, internet radio, and extensive library management.

Setup Guide (Volumio)

1. Flash the Image

Download the Volumio image for Raspberry Pi. Use Balena Etcher to flash it to the microSD card. Insert the card into the Pi.

2. Connect Hardware

If using a DAC HAT, install it onto the GPIO pins before powering on. Connect the DAC output to your amplifier via RCA cables. Connect Ethernet. Connect power.

3. Initial Configuration

Open a browser and navigate to volumio.local (or the Pi’s IP address). The setup wizard walks through language, DAC selection, and network configuration. Select your specific DAC HAT model from the list.

4. Add Music Sources

Streaming: Configure Spotify Connect, Tidal Connect, or AirPlay in the Sources settings. Spotify Connect appears as a playback device in the Spotify app. AirPlay appears on Apple devices automatically.

Network shares: Add your NAS or shared folder path in the Network Drives settings. Volumio scans the share and indexes your music library.

USB drive: Plug a USB drive containing music files. Volumio detects and indexes it automatically.

5. Play

Open the Volumio interface from any device on your network. Browse your library, queue tracks, and control playback. The Pi runs headless (no monitor needed) and streams continuously.

Sound Quality Considerations

The Raspberry Pi itself is just a computer that sends digital audio data to the DAC. The sound quality depends entirely on the DAC (either the HAT or your external USB DAC) and the analog output stage.

A $45 HiFiBerry DAC2 Pro measures well and produces clean analog output that competes with standalone DACs costing $100-$200. For most listeners in a normal living room, this is indistinguishable from higher-priced streamers.

The Pi’s USB output works well with quality USB DACs. The Linux kernel handles USB audio reliably, and bit-perfect output is achievable with proper software configuration.

Key Takeaways

  • A Raspberry Pi 4 with a DAC HAT creates a capable network streamer for $100-$150
  • Volumio provides the easiest setup with streaming service integration and a polished web interface
  • moOde Audio offers more configuration for advanced users
  • The DAC HAT determines sound quality, not the Pi itself
  • Wired Ethernet is recommended for reliable uninterrupted streaming
