How do I turn a Raspberry Pi 4 or 5 into a Hi-Res music streamer?

Download the free 64-bit ConduitServerOS image, flash it to a microSD card or NVMe SSD using Raspberry Pi Imager (Choose OS -> Use custom), boot your Raspberry Pi 4 or 5, and complete the 5-step browser onboarding wizard at conduit.local.

Is Conduit Audio bit-perfect and what DACs are supported?

Yes. Conduit Audio routes 192kHz/32-bit PCM audio directly to ALSA hardware devices with zero OS mixer resampling, supporting USB Audio Class 2.0 DACs, HiFiBerry/Allo/IQaudio I2S HATs, and HDMI outputs.

Does Conduit Audio require a monthly cloud subscription or internet connection?

No. The core Conduit OS streamer is 100% free forever, and Studio Pro ($0) uses an offline Ed25519 cryptographic license key verified locally on your Raspberry Pi with zero cloud logins or recurring monthly subscriptions.

Can I synchronize multi-room audio across multiple Raspberry Pi rooms?

Yes. Flash ConduitNodeOS onto additional Raspberry Pi units around your home; Conduit automatically discovers each room via mDNS and synchronizes playback with sub-millisecond precision.
