The previous default EDID did not advertise audio capabilities,
preventing HDMI audio capture from working. This update ensures
the JetKVM properly identifies itself to source devices and
enables audio capture out of the box.
Changes:
- Display identifies as "JetKVM HDMI" (manufacturer ID: JTK)
- Includes full audio support (2/6/8-channel LPCM, up to 192 kHz)
- Advertises all TC358743XBG capabilities (1080p60, YCbCr, Deep Color)
This allows HDMI audio to work by default without manual EDID
configuration.
Browser autoplay policy blocks audio without user interaction.
Store audio elements in ref and trigger playback when user clicks
the existing 'Manually start stream' button.
This should ensure that newly added strings are kept in their correct location so later changes yield clean GIT diffs.
Also bumped a couple minor dependencies

- Revert .golangci.yml to dev branch state (removed custom build-tags)
- Remove internal/audio/cgo_source_stub.go (not needed with proper cross-compilation)
- Fix import ordering in ui/src/utils.ts
Use 'make lint-go' for proper ARM cross-compilation environment.
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.$id.settings.audio.tsx:
- Import and use translation keys (m.audio_settings_*)
- Use existing audio_output_* and audio_input_* keys for notifications
- Fix dropdown not updating: update UI optimistically, revert on error
- This prevents the dropdown from appearing stuck after source change
The optimistic update pattern improves UX by immediately reflecting
the user's choice while the backend processes the change.
- Resolved conflicts in .gitignore, ActionBar, UsbDeviceSetting, and devices.$id.tsx
- Added audio-related translations to all language files:
- action_bar_audio
- usb_device_enable_audio_title
- usb_device_enable_audio_description
- usb_device_keyboard_mouse_mass_storage_and_audio
- Updated UI components to use localization messages
- Added separate USB preset for keyboard/mouse/storage without audio
- Kept OPUS_STEREO_PARAMS import from audio branch
- Preserved AudioPopover component from audio branch
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.
Audio quality improvements:
- Enable constrained VBR to prevent bitrate starvation at low volumes
- Increase Opus complexity from 2 to 5 for better quality
- Enable DTX for bandwidth optimization
- Enable FEC (Forward Error Correction)
- Add DTX and FEC signaling in SDP (usedtx=1;useinbandfec=1)
Default configuration changes:
- Change default audio output source from HDMI to USB
- Enable USB Audio device by default
- USB audio works on current stable image (HDMI requires newer device tree)
These changes fix crackling issues at low volumes and provide better
overall audio quality for both USB and HDMI audio paths.

Add SVG and ICO to cacheable files.
Emit robots.txt directly.
Recognize WOFF2 (font) files as assets (so the get the immutable treatment)
Pre-gzip the entire /static/ directory (not just /static/assets/) and include SVG, ICO, and HTML files
Ensure fonts.css is processed by vite/rollup so that the preload and css reference the same immutable files (which get long-cached with hashes)
Add CircularXXWeb-Black to the preload list as it is used in the hot-path.
Handle system-driven color-scheme changes from dark to light correctly.
Ensure the jiggler config loads the defaults so they can be saved.
Ensure the file.Sync occurs before acknowledging save.
