San Andreas Radio · San Andreas Sound Suite Documentation

01 / Overview

State, sources, and authority

Radio owns vehicle eligibility, permissions, synchronized source and station selection, power, volume intent, timestamps, metadata, Bluetooth transport, scanner power, and the head-unit interfaces. The selected provider only renders that state.

Source	Media owner	Synchronization model
Local Radio	GTA V	Native station, power, and track metadata are synchronized; GTA owns playback gain.
Satellite Radio	External stream operator	Vehicle state is synchronized; matching live URLs can share a provider syncGroup.
Server Radio	Configured Station Pack	One deterministic program clock supplies a seekable track and offset.
Bluetooth	Player-supplied supported URL	Vehicle queue, URL, transport position, play state, and revision are synchronized.
Scanner	Local Dispatch or configured live profile	Separate vehicle channel, power state, public metadata, and HUD.

The server validates the real requesting player, networked vehicle, seat permission, vehicle eligibility, station or URL, source, and rate limit before changing shared state. NUI state is never an authority boundary.

New vehicle state is powered off by default. Normal entertainment restrictions and scanner eligibility are independent so emergency controls can remain available while the entertainment UI is blocked.

02 / Setup

Requirements and installation

Keep the exact san_andreas_radio folder name.
OneSync is required and declared by dependency '/onesync'.
Radio has no framework, database, npm-install, or build requirement.
Start the selected audio provider before Radio. Start optional Dispatch and Station Packs before Radio when their sources are used.
Without Dispatch, only scanner profiles with a non-empty URL can play. Without Station Pack, Local, Satellite, and Bluetooth remain available.

ensure san_andreas_sound
ensure san_andreas_dispatch
ensure san_andreas_station_pack
ensure san_andreas_radio

Confirm OneSync, start order, and a clean server console.
Enter a normal vehicle, start the engine, and open the head unit with Q or /saradio.
Confirm the radio begins powered off, then test every installed source.
Confirm the mini display follows radio, engine/accessory, and pause state.
Enter a restricted emergency vehicle and confirm the entertainment UI remains blocked.
Enter an eligible scanner vehicle and verify its scanner power and HUD separately.

03 / Configuration

Core state, permissions, and lifecycle

Key	Type	Default	Accepted values	Description
`Config.OpenKey`	`string`	`Q`	—	Default player-remappable head-unit key.
`Config.HoldToOpen`	`boolean`	`false`	—	Uses hold behavior when true and toggle/Escape behavior when false.

engine running + radio on
-> engine off: accessory state remains active
-> driver door opens: radio powers down and remembers state
-> later engine start: remembered source and station restore

Bluetooth resumes from its retained position only when it had been playing before shutdown. The engine-stop and entity-resolution grace periods prevent brief native-state or network-entity flicker from destroying and recreating media.

04 / Interface

Displays and controls

`MiniRadio.MinScale / MaxScale`	`number`	`0.70 / 1.50`	Player resize bounds.
`AccentPicker.Enabled`	`boolean`	`true`	Lets players save a fixed display accent or choose AUTO.
`AccentPicker.DefaultColor`	`hex color`	`#41d9ff`	Fallback accent for the display.
`ScannerHud.VisibleByDefault`	`boolean`	`true`	Initial local HUD preference.

`Config.Audio.PositionUpdateMs`	`number`	`350`	Compatibility provider position update interval.

06 / Native source

Local GTA Radio

Config.Stations controls which valid native GTA station IDs appear and in what tuner order. Removing an entry hides it from this UI. Radio reads GTA's active track text ID, resolves built-in labels, validates the driver as metadata publisher, and shares the result with occupants.

Optional artwork is a local JPG under san_andreas_radio/web/assets/stations. Without an explicit filename, the NUI derives a lowercase label slug. Add manifest patterns before using other artwork extensions.

`Config.Metadata.PollMs`	`number`	`750`	Client native-track polling interval.
`Config.Metadata.RetuneDelayMs`	`number`	`1000`	Delay before accepting metadata after tuning.
`Config.Metadata.ServerRateLimitMs`	`number`	`400`	Minimum server interval for validated metadata updates.
`Config.Metadata.DebugCommand`	`string`	`saradiotrack`	F8 diagnostic command.
`Config.TrackMetadata[id]`	`table`	—	Optional title/artist correction for missing GTA labels.

07 / External streams

Satellite Radio and now-playing metadata

Confirm permission for the intended server use and distribution of configuration and artwork.
Find a direct browser-playable endpoint rather than a web-player page. Prefer stable HTTPS MP3, AAC, OGG, or browser-playable HLS without login, cookies, or expiring tokens.
Test the exact endpoint in FiveM's embedded browser environment.
Prepare locally hosted, authorized station artwork and add the station to the active Config.Streams table.
Add JSON or SSE metadata mapping when available, or provide Config.StreamMetadata fallback text.
Restart Radio, test inside/outside behavior and cleanup, and compare two vehicles on the same live station.

One Config.Streams entry
Key	Type	Default	Required	Description
`id`	`string`	—	Yes	Unique synchronized identity; an uppercase SATELLITE_ prefix is recommended.
`label`	`string`	—	—	Full station name.

`artwork`	`string`	—	—	Radio-owned JPG filename under web/assets/stations.
`url`	`URL`	—	Yes	Direct media endpoint.
`metadata`	`table`	—	—	Optional JSON polling or SSE definition.

Metadata definition fields
Key	Type	Default	Accepted values	Required	Description
`type`	`string`	—	`json \| sse`	Yes	Transport used for now-playing data.
`url`	`HTTPS URL`	—	—	Yes	CORS-enabled metadata endpoint.
`pollMs`	`number`	—	—	—	Clamped JSON polling interval; do not use it as high-frequency telemetry.
`dataPath`	`dot path`	—	—	—	Selects the record or list containing current data.
`station / stationPath`	`string / dot path`	—	—	—	Selects one station from a shared feed.
`artistPath / titlePath / idPath`	`dot path`	—	—	—	Maps separate artist, title, and stable update ID fields.
`combinedPath / separator`	`dot path / string`	—	—	—	Splits one combined Artist - Title field.
`fallbackArtistPath / fallbackTitlePath`	`dot path`	—	—	—	Program-level fallback fields when song values are absent.

The stream plays but fallback text never updates.

Likely causes

Metadata CORS is blocked
The response path is wrong
The endpoint is not HTTPS

Checks

Inspect the exact response
Correct data/artist/title paths
Test endpoint CORS in FiveM CEF

Expected result

Validated now-playing fields synchronize to occupants.

The feed selects the wrong station record.

Likely causes

station and stationPath are missing or incorrect

Checks

Map the shared feed's station key

Expected result

The configured station record is selected before metadata paths are read.

Two vehicles drift on one live station.

Likely causes

SyncSatelliteStreams is disabled
The provider ignores syncGroup
CORS forced HTML fallback

Checks

Confirm matching URL/group and webaudio diagnostics

Expected result

A compatible provider fans one live decode into independent vehicle branches.

08 / Scanner

Scanner profiles and Dispatch mapping

Desired source	Dispatch mapping	Profile URL
Local Dispatch only	Map profile to channel	May remain empty.
External stream only	Leave unmapped or disable Dispatch	Required direct URL.
Local Dispatch with fallback	Map profile to channel	Required direct fallback URL.
YouTube live fallback	Either mapped or unmapped	Supported channel /live URL with resolver enabled.

Config.ScannerProfiles entry
Key	Type	Default	Required	Description
`Id`	`string`	—	Yes	Stable lowercase profile ID used by power and Dispatch mapping.
`Enabled`	`boolean`	`true`	—	Profile master switch.
`Url`	`URL`	—	—	External source or fallback; may be empty for a mapped local channel.
`ResolveYouTubeLive`	`boolean`	`false`	—	Resolve a supported YouTube channel /live page.
`YouTubeRefreshMinutes`	`number`	`10`	—	Live-page refresh interval.
`Label / HudLabel`	`string`	—	Yes	Full channel name and compact receiver heading.
`HudAccent`	`#RRGGBB`	—	Yes	Scanner display color.
`Volume`	`number`	`0.10`	—	In-cabin scanner source level.
`RequireEngine`	`boolean`	`false`	—	Require an active engine.
`DisableNativeScanner`	`boolean`	`true`	—	Suppress GTA scanner for this profile.
`Loop`	`boolean`	`true`	—	Loop continuous external profiles; local Dispatch descriptors remain non-looping.
`VehicleModels`	`array`	—	—	Explicit spawn names checked before broad classes.
`VehicleClasses`	`array`	—	—	Broad GTA class eligibility.
`DisabledModels`	`array`	—	—	Hard exclusions applied before profile matching.
`MaxDistance`	`number`	`20.0`	—	Scanner radius.
`MuffleOutsideVehicle`	`boolean`	`true`	—	Apply provider exterior shaping.
`ExteriorVolumeMultiplier`	`number`	`0.30`	—	Exterior scanner trim; marine defaults to 0.50.
`ExteriorMaxDistance`	`number`	`10.0`	—	Exterior scanner radius.
`EngineStopGraceMs`	`number`	`1200`	—	Avoid brief lifecycle churn.

GTA class or strategy	Typical profile
Explicit model before broad class	Fire apparatus and ambulances before the class 18 emergency fallback.
18	Police/general emergency fallback.
15 and 16	Aviation.
14	Marine.
17 and 20 plus explicit utility models	Service/commercial.

Profiles are evaluated in order. Explicit VehicleModels win before broad VehicleClasses, and a model listed in any enabled profile's DisabledModels receives no configured scanner.

For local Dispatch, Config.Dispatch.ProfileChannels maps Radio profile IDs to Dispatch channel IDs. A healthy local descriptor takes priority; a profile URL is used only when the profile is unmapped or its mapped source is unavailable.

Restart Dispatch after catalog changes and Radio after profile or mapping changes.
Enter an explicitly listed model and confirm it wins over a broad class profile.
Verify channel, system, talkgroup, destination, frequency, and STANDBY/RECEIVING state.
Toggle scanner power with the key, /sascanner, and conditional head-unit control; use /scannerhud to test local visibility only.
Confirm GTA's native scanner is suppressed only where intended.
Stop Dispatch temporarily only when intentionally testing a configured URL fallback.
Test engine state, exit/re-entry, pause, deletion, and independent restarts.

09 / Server Radio

Register Station Packs

Key	Type	Default	Description
`Config.ServerRadio.Enabled`	`boolean`	`true`	Makes Server Radio available when a valid pack is running.
`Config.ServerRadio.AcousticClass`	`string`	`server_music`	Optional provider hint for peak-controlled local media.
`Config.ServerRadio.VolumeMultiplier`	`number`	`0.70`	Inside-and-outside trim for locally hosted station media.
`Config.ServerRadio.ExteriorVolumeMultiplier`	`number`	`0.75`	Additional exterior trim after normal Radio exterior shaping.
`Config.ServerRadio.Resources`	`array`	`{ 'san_andreas_station_pack' }`	Exact installed station-pack resource names.

Install each pack beside Radio and start it before Radio.
Append each exact folder name to Config.ServerRadio.Resources; do not overwrite other needed packs.
Confirm every pack exposes GetStations and GetSnapshot and emits the local stationPackChanged event.
Restart the pack and then Radio, choose the SERVER source, and verify catalog, artwork, metadata, and audio.
Tune two vehicles at different times and confirm the same program offset; restart only the pack and confirm its stable clock reconstructs the schedule.
Normalize local media before adjusting the two Server Radio trims.

10 / Bluetooth

Bluetooth playlists and URL security

Key	Type	Default	Accepted values	Description
`Config.Bluetooth.Enabled`	`boolean`	`true`	—	Enables player-supported URL playback.
`FetchVideoTitles`	`boolean`	`true`	—	Uses YouTube oEmbed to resolve presentation titles.
`AllowDirectUrls`	`boolean`	`false`	—	When false, restricts URLs to the configured host allowlist.
`AllowHttp`	`boolean`	`false`	—	Rejects insecure HTTP by default.
`MaxUrlLength`	`number`	`512`	—	Maximum accepted submitted URL length.
`AllowedHosts`	`array`	—	—	Approved YouTube and youtube-nocookie hosts in the release config.
`Playlist.Enabled`	`boolean`	`true`	—	Enables saved multi-link lists.
`Playlist.MaxTracks`	`number`	`30`	—	Player saved-list cap; Radio's effective safety maximum is 100.
`Playlist.AllowDuplicates`	`boolean`	`false`	—	Controls repeated URLs.
`Playlist.AutoAdvance`	`boolean`	`true`	—	Advances after provider-reported natural completion.
`Playlist.RepeatMode`	`string`	`all`	`off \| all \| one`	Default repeat behavior.
`Playlist.ShuffleByDefault`	`boolean`	`false`	—	Default local shuffle preference.

The full saved playlist remains in the player's local KVP. The server receives a validated transient queue for the active vehicle; other occupants receive only current media and the queue summary needed for synchronization.

The server rejects credentials, whitespace, control characters, unsupported schemes, overlong values, and unapproved hosts. Client or NUI validation is only feedback; the server revalidates every request and the real vehicle/seat authority.

Natural completion advances the queue once. A changing Bluetooth revision rejects duplicate completion reports from multiple listeners; intentional destroy or replacement must not invoke auto-advance.

11 / Voice integration

PMA live-player scanner bridge

The optional bridge rebroadcasts selected pma-voice radio channels into powered vehicle scanners without joining listeners to the talker's channel or modifying their PMA radio/call state.

Key	Type	Default	Accepted values	Required	Description
`LiveVoiceScanner.Enabled`	`boolean`	`false`	—	—	Leave disabled until mappings and privacy behavior pass a multiplayer test.
`Provider / Resource`	`string`	`pma_voice / pma-voice`	—	—	Selected internal voice adapter and resource folder.
`VoiceTarget`	`number`	`1`	`1-32`	—	PMA receive target used by the adapter.
`Volume`	`number`	`0.22`	—	—	Scanner voice level.
`UseSubmix`	`boolean`	`true`	—	—	Requests the configured PMA voice treatment.
`NaturalVoiceDistance`	`number`	`4.0`	—	—	Avoids duplicate scanner routing when the talker is naturally audible.
`DispatchDuckMultiplier`	`number`	`0.20`	—	—	Lowers scheduled Dispatch while live voice is active.
`MaxTransmissionMs`	`number`	`120000`	—	—	Releases a stuck transmission.
`ShowPlayerName`	`boolean`	`false`	—	—	Privacy-preserving default; true sends the current server name to eligible listeners.
`ProfileChannels`	`map`	—	—	Yes	Maps scanner profile IDs to positive PMA channel definitions with labels, frequency, and priority.

Start pma-voice before Radio when the bridge is enabled.
A talker must actively transmit on a configured PMA channel; a listener must occupy a powered matching scanner vehicle.
Radio avoids a duplicate path when listener and talker share the PMA radio channel, share a call, or are within NaturalVoiceDistance.
One talker is selected per vehicle. Higher profile priority wins; optional Range can constrain reach. Keep channel numbers unique because the first duplicate definition wins.
Set UseSubmix=false temporarily when isolating provider or submix behavior.

Put client A on one mapped PMA radio channel.
Put client B in an eligible powered scanner vehicle, on a different PMA channel or none, and move beyond natural voice range.
Transmit from A and confirm B hears the scanner route and sees the configured metadata.
Move B onto A's channel, then within natural range, and confirm no obvious duplicate path.
Test Dispatch ducking, scanner off, exit, deletion, talker disconnect, timeout, and independent resource restarts.
Test player-name display both ways, then restore the intended privacy setting.

12 / API

Public cross-resource contract

`GetVehicleRadioState`

exportServer

Return the suite-managed raw state for one networked vehicle. Copy needed fields immediately and never mutate or retain the returned table.

GetVehicleRadioState(vehicleNetId)

Returns: nil or raw read-only state table

State includes station, mode, volume, powered, accessory, spatial, track, Bluetooth, and revision.
Radio exposes no supported external setter, callback, or outward state-change event.
Internal san_andreas_radio network events are validated player-action implementation details, not public automation APIs.

State area	Fields
Core	station, mode, volume, powered, accessory, spatial, revision
Track	false or { id, title, artist, source }
Bluetooth	url, label, playing, base position, startedAt, and revision

13 / Operations

Diagnostics and troubleshooting

The head unit will not open.

Likely causes

OneSync or lifecycle state
Vehicle restriction
Seat permission
Key mapping

Checks

Confirm current vehicle/seat
Check engine/accessory state and restrictions
Try /saradio

Expected result

An eligible occupant opens the UI and the server accepts validated state requests.

The mini display stays hidden.

Likely causes

Radio power off
Engine/accessory state
Pause state
Local MINI preference

Checks

Power on the radio
Restore engine/accessory eligibility
Check the local preference

Expected result

The display appears only while its lifecycle allows it.

A Satellite station is silent.

Likely causes

Not a direct media URL
HTTPS/codec/provider failure
Browser embedding or CORS behavior

Checks

Test the exact endpoint
Inspect F8 and Sound diagnostics

Expected result

The provider confirms playback through webaudio, html, or documented YouTube fallback.

A scanner never appears or uses the wrong source.

Likely causes

Profile order or disabled model
Missing mapping with blank URL
Class/model spelling
Dispatch unavailable

Checks

Inspect selected profile and mapping
Test explicit model precedence
Check channel state and fallback URL

Expected result

The intended eligible profile supplies local Dispatch or its configured external source.

GTA and replacement scanners both play.

Likely causes

DisableNativeScanner is false on the selected profile

Checks

Correct the matching profile, not a different profile

Expected result

Native chatter is suppressed only for intended replacement profiles.

Server Radio starts from zero or is too loud.

Likely causes

Incorrect final duration or seek path
Hot local mastering
Trims too high

Checks

Verify Station Pack snapshot and duration
Inspect Sound start confirmation
Normalize media and lower both Server Radio trims

Expected result

Late listeners seek to the current offset at a balanced level.

Bluetooth stops after one track.

Likely causes

AutoAdvance disabled
Provider does not report natural completion
Intentional replacement incorrectly calls onPlayEnd

Checks

Inspect Playlist.AutoAdvance and provider callback semantics

Expected result

Exactly one natural completion advances the queue.

Audio duplicates after restart.

Likely causes

More than one provider instance
Provider or caller cleanup does not own names correctly

Checks

Run one selected provider
Restart each resource separately and inspect remaining diagnostics

Expected result

Resource restart removes only owned playback and leaves no duplicate.

Complete the full control, source, tuner, playlist, permission, lifecycle, UI, and scanner pass with at least two clients and two vehicles.
Test same and different Satellite stations, every installed Dispatch profile, Station Pack late joining, and PMA routing when enabled.
Restart Sound, Dispatch, Station Pack, and Radio independently and confirm unrelated vehicle resources continue running.
