- Update default EDID with registered manufacturer ID (Dell) and proper 24-inch display dimensions (52x32cm) for better macOS/OS compatibility
- Add configurable sample rate (32/44.1/48/96 kHz) to support different HDMI audio sources
- Add packet loss compensation percentage control for FEC overhead tuning
- Fix config migration to ensure new audio parameters get defaults for existing configs
- Update all language translations for new audio settings
- Add config fields for bitrate, complexity, DTX, FEC, buffer periods
- Add RPC methods for get/set audio config and restart
- Add UI settings page with controls for all audio parameters
- Add Apply Settings button to restart audio with new config
- Add config migration for backwards compatibility
- Add translations for all 9 languages
- Clean up redundant comments and optimize log levels
- Add AudioInputAutoEnable and AudioOutputEnabled fields to backend config
- Implement RPC methods for get/set audio input auto-enable preference
- Load audio output enabled state from config on startup
- Make manual microphone toggle call backend to enable audio pipeline
- Auto-enable preference now persists across incognito sessions
- Reset microphone state to off when reaching login pages
- Fix issue where manual mic toggle required auto-enable to be on
Implement session-based microphone control with optional auto-enable:
- Microphone disabled by default, only requests permission when enabled
- Added persistent "Auto-enable Microphone" setting in audio settings
- Setting syncs to backend and works across browsers/devices
- Auto-enable respects secure context (HTTPS/localhost only)
- Refactored secure context check into reusable utility function
- Removed unused audioInputEnabled store properties
Temporarily remove the ability to switch between HDMI and USB audio
output sources. The application now uses USB audio (hw:1,0) exclusively
until HDMI audio capture issues are resolved.
Changes:
- Remove AudioOutputSource config field
- Remove audio source switching logic and UI
- Hardcode USB audio output device
- Remove related RPC methods
After setting audio output source, fetch the actual value from backend
to verify the change was applied successfully. This prevents the UI
from showing incorrect state when the backend fails to apply the change.
The optimistic update provides immediate feedback, but we now verify
the actual result and show error if backend returned a different value
than expected.
Added comprehensive translations for audio settings page:
- Page title and description
- Audio output/input settings
- Audio source selector (HDMI/USB labels)
- Success/error messages for all operations
- Translations added for all 9 languages
Updated devices.$id.settings.audio.tsx:
- Import and use translation keys (m.audio_settings_*)
- Use existing audio_output_* and audio_input_* keys for notifications
- Fix dropdown not updating: update UI optimistically, revert on error
- This prevents the dropdown from appearing stuck after source change
The optimistic update pattern improves UX by immediately reflecting
the user's choice while the backend processes the change.
Remove all subprocess-based audio code to simplify the audio system and
reduce complexity. Audio now uses CGO in-process mode exclusively.
Changes:
- Remove subprocess mode: Deleted Supervisor, IPCSource, embed.go
- Remove audio mode selection from UI (Settings → Audio)
- Remove audio mode from backend config (AudioMode field)
- Remove JSON-RPC handlers: getAudioMode/setAudioMode
- Remove Makefile targets: build_audio_output/input/binaries
- Remove standalone C binaries: jetkvm_audio_{input,output}.c
- Remove IPC protocol implementation: ipc_protocol.{c,h}
- Remove unused IPC functions from audio_common.{c,h}
- Simplify audio.go: startAudio() instead of startAudioSubprocesses()
- Update all function calls and comments to remove subprocess references
- Add constants to cgo_source.go (ipcMaxFrameSize, ipcMsgTypeOpus)
- Keep update_opus_encoder_params() for potential future runtime config
Benefits:
- Simpler codebase: -1,734 lines of code
- Better performance: No IPC overhead on embedded hardware
- Easier maintenance: Single audio implementation
- Smaller binary: No embedded audio subprocess binaries
The audio system now works exclusively via CGO direct C function calls,
with ALSA device selection (HDMI vs USB) still configurable via settings.
