Status was a value-typed DeviceStatus field on DeviceConnection,
written from the periodic poller (UpdateDeviceStatus) and from four
WebSocket event handlers (OnNowPlaying, OnVolumeUpdated,
OnConnectionState, OnPresetUpdated) while being read from every HTTP
handler and the WebSocket broadcaster. The struct was 8+ words wide
with time.Time and string members, so concurrent readers could
observe torn fields or mixed-update snapshots. The map-level race was
fixed in the previous commit; this one closes the per-connection
struct race.
Hide the field behind atomic.Pointer[DeviceStatus]:
Status() // returns current snapshot
SetStatus(*DeviceStatus) // wholesale replace
UpdateStatus(func(*DeviceStatus)) // CAS retry loop
NewDeviceConnection constructs a connection with the atomic pointer
pre-initialised, so Status() never returns nil for callers that go
through the constructor (the old struct-literal pattern is no longer
possible because the status field is now private).
UpdateDeviceStatus runs network fetches into local vars first, then
batches them into a single UpdateStatus call so the CAS loop only
retries the merge — not the slow IO. WebSocket event handlers and
the connect/disconnect transitions each use UpdateStatus, so any
ordering of poller + event delivery converges to a consistent
status.
The UpdateStatus docstring is explicit about the shallow-copy
contract: nested pointer fields (NowPlaying, Volume, Bass, Presets,
Sources) MUST be replaced, not mutated through, because the copy
mut receives shares those pointers with the prior snapshot. All
production callers already follow this pattern (every value comes
fresh from the device API).
Tests:
- types_test.go: migrated literal struct to NewDeviceConnection +
SetStatus, switched reads to Status().
- status_test.go (new): six tests covering constructor init,
SetStatus replacement semantics, UpdateStatus mutator
application, field preservation across UpdateStatus, snapshot
isolation (old snapshot stable under later writes), and a
concurrent stress test (16 writers + 32 readers x 200 ops) that
runs under -race.
- handlers_test.go, registry_test.go, spa_test.go: migrated to
constructor.
Not addressed by this commit:
- DeviceConnection.WebSocket (set once in ConnectDeviceWebSocket,
read elsewhere). Word-sized pointer, atomic at the hardware
level on amd64/arm64; race detector may still flag.
- DeviceConnection.LastSeen (written under devicesMu by the
registry, read outside that lock via DeviceSnapshot consumers).
time.Time is non-atomic but the read is cosmetic.

Bose SoundTouch Toolkit
Independent project. Not affiliated with or endorsed by Bose Corporation.
Context: Cloud Shutdown
Bose is shutting down SoundTouch cloud services on May 6, 2026. After that, music service browsing, preset sync, and the official SoundTouch app stop working. This toolkit lets you keep your speakers fully functional.
See the Survival Guide for the full picture.
Tools
soundtouch-service — AfterTouch
A local server that replaces the Bose cloud ("AfterTouch"). Once your speaker is redirected to it, you have full control without any Bose cloud dependency. The built-in web UI at http://localhost:8000 handles all setup — no config files needed to get started.
If you want to run a server for this - no problem. The service is small enough to run on the SoundTouch itself. See the On-Device Installer for instructions.
Two scenarios:
Before shutdown — migrate your existing setup
While the Bose cloud is still running, use soundtouch-backup to save your account data. The local service web UI then helps with the migration so your speaker keeps its presets and credentials.
After shutdown or factory reset — start fresh Create a local account, configure your speakers, and start using them immediately. No Bose infrastructure required.
Redirecting your speaker
The service needs a stable address on your local network (e.g. soundtouch.fritz.box or soundtouch.local). The speaker must then be redirected to resolve the Bose cloud hostnames to that address. Two supported methods:
| Method | How it works | Notes |
|---|---|---|
| XML redirect | Upload a config XML via the Web API | Surgical; covers only registered endpoints; best for testing |
| DNS/DHCP | Serve custom DNS on your network | Covers all devices at once; requires port 53 and TLS |
The web UI walks you through each method. DNS redirect requires HTTPS — the service manages its own CA certificate and the web UI guides you through trusting it on each speaker.
Note: A hosts-file method (direct SSH edits to
/etc/hosts) also exists in the codebase but is deprecated and not exposed in the web UI.
Enabling SSH via USB stick
Some setup steps require SSH access to the speaker. Enable it once per device: create a file named remote_services on a FAT-formatted USB drive (the drive may need its bootable flag set — see SoundCork issue #172), and insert it while the speaker is powered on. After reboot, root SSH is available with no password.
See Device Initial Setup and Migration Guide for step-by-step instructions.
soundtouch-backup
Backs up your Bose cloud account (presets, paired devices, music sources) and each speaker's local state before the shutdown. Run soundtouch-backup all to capture everything in one step; it authenticates with the Bose cloud, then polls each paired speaker over the local network.
See the soundtouch-backup README for usage.
soundtouch-cli
Command-line control of any SoundTouch device: play/pause/volume, presets, source selection, multiroom zones, device discovery, and more. Works entirely over the local network — no cloud dependency. Well-suited for scripting and home automation.
See the CLI Reference for full usage.
soundtouch-web
A standalone web UI for device control — play, pause, volume, preset selection, real-time status — served from a local Go binary. Complements soundtouch-service when you want a dedicated device-control interface separate from the setup/admin UI.
See the soundtouch-web README for usage.
Go library
pkg/client provides a Go API for all SoundTouch device endpoints: media control, volume, presets, sources, zones, real-time WebSocket events, and device discovery. Use it to build your own integrations.
