Sendspin

Sendspin

Sendspin is Ava's integration with Music Assistant for multi-room audio synchronization. It enables multiple Ava devices to play music in sync across rooms.

Overview

Sendspin allows Ava to act as a Music Assistant player, receiving audio streams and synchronizing playback across multiple devices on the same local network.

Features:

• Multi-room audio sync
• Opus and PCM audio format support
• Adjustable sync offset for fine-tuning
• Low memory mode for older devices
• Device or software volume control
• FLAC and Opus decoding

Setup

Prerequisites

1. Music Assistant installed and running in Home Assistant
2. Ava devices on the same LAN as Music Assistant

Enable Sendspin

1. Go to Settings -> Extensions -> Playback -> Media Player
2. Turn on Music Assistant Media Controls
3. Set the Sendspin Device Name (leave empty to use system device name)
4. Choose Sendspin Audio Format (Automatic recommended)
5. Ava will appear as a player in Music Assistant

Note: Sendspin device names are customizable. Saving triggers a session restart so Music Assistant refreshes the display name faster. If the old name persists, refresh the player in Music Assistant or fully kill and restart Ava.
