# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/).

## [Unreleased]

### Fixed
- Play() deadlocks when called before device is open (recursive SwitchDevice → Play)
- Audio volume silently zeroed after switching output devices (Init used hardcoded 0.20; SwitchDevice did not restore saved volume)
- SwitchDevice not persisted to database across restarts (caller now saves to AppConfig)
- Device restore path passes invalid device name "system default" to SDL (now passes "" for default)
- Stop() no-op when audio toggled off mid-playback (removed AudioEnabled guard from Stop)
- App shows "READY" before audio files finish downloading (state machine now gates READY on download completion via DOWNLOADING_ASSETS state)
- Download failure no longer silently allows READY (downloadFailed flag prevents premature READY)

### Known Issues
- Active device highlight incorrect when using default device

### Added
- Human-readable audio device names (Built-in Speakers, HDMI/TV/Monitor)
- Unit tests for mixer package (parseSinks, parseSinkLine, ConvertVolume)
- Regression tests for state machine (download gating, failure handling)
- Regression tests for mixer (Stop with AudioEnabled=false, SwitchDevice edge cases)

### Changed (Major Refactors)
- Mixer package: inject audio backend dependencies for testability
- Mixer package: extract wpctl calls behind an interface
- SwitchDevice now takes *db.AppConfig to access saved volume
- Audio files moved from ~/.local/share/rhemawave/audio to ~/.radiantwave/audio
- State machine uses DOWNLOADING_ASSETS state before READY
- CI now runs go test before nix build
