CodeQL flagged "uncontrolled data used in network request": the
soundtouch-web TTS proxy built its outbound request URL from the
client-supplied serviceUrl, letting any LAN caller use the endpoint as an
SSRF proxy. The proxy target must be the operator-configured --service-url.
- handler: use only app.ServiceURL; drop the client-supplied serviceUrl
field and fallback.
- web TTS view: show the configured service URL read-only with an
explanation of why it can't be edited here (Play URL differs — its URL
is handed to the speaker, not fetched by soundtouch-web, so no SSRF).
- api.speak no longer sends serviceUrl.

soundcork#104 confirms speakers validate the /speaker audio-notification
app_key against audionotification.api.bosecm.com (100 calls/day on real
Bose). Our /v1/auth shim accepts it, but a host-seeded migration only
worked if the speaker resolved that host to us. DNS interception already
covers it (bosecm.com substring), but the /etc/hosts migration domain
list did not — so the speaker method would fail on hosts-based setups.
Seed both audionotification.api.bosecm.com and the dev variant
(audionotificationdev.api.bosecm.com; firmware may use either) into the
migration /etc/hosts lists, and update the mock fixtures/docs accordingly.
/v1/auth is path-based, so it already answers regardless of which host the
speaker thinks it is calling.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Confirmed working on a real speaker (Bose_Lisa/27.0.6): the speaker GETs
/v1/auth at audionotification.api.bosecm.com (DNS-redirected to us) with
the app_key in an "Apikeyheader" header, and an empty 200 is sufficient.
- Make "speaker" the default playback method (ducks + resumes the current
playback, supports volume) for the speak endpoint, the CLI --method flag,
and the web UI button; "radio" remains opt-in.
- Remove the temporary full-request debug dump from /v1/auth now that the
contract is understood; document it in the handler comment instead.

Replaces the awkward top-level `tts speak --speaker-host` with a
`speaker tts-cloud` subcommand that sits alongside the existing
`speaker tts` and uses the global --host flag (--device still works as
an alternative). The two are now clearly related: `speaker tts` sends a
Google Translate URL straight to the speaker, while `speaker tts-cloud`
routes through the service for server-side synthesis (Cloud TTS) and
playback. --speaker-host is gone.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The TTS speak/config endpoints were under /mgmt (Basic-Auth protected),
but the soundtouch-web proxy and CLI authenticated with their own
mgmt-password default (empty) while the service defaults to "change_me!",
so speaking from -web returned 401.
This was also inconsistent: the Google API key is configured via the
unauthenticated /setup/settings, and Play URL already proxies to /setup,
so gating only TTS playback behind mgmt auth made no sense. Move
/mgmt/tts/{speak,config} to /setup/tts/{speak,config} (LAN-trust, like
the rest of the setup surface), rename the handlers accordingly, and drop
the now-unused mgmt-credential plumbing from soundtouch-web and the CLI
tts command.
Verified: POST /setup/tts/speak now reaches the handler without auth
(502 only because the test speaker IP is unreachable; previously 401).

Adds text-to-speech that synthesizes higher-quality audio (Google Cloud
TTS) and plays it on a speaker via the /speaker endpoint. Because Cloud
TTS returns audio bytes (not a fetchable URL), the service caches the
clip and hosts it at GET /media/tts/{id}, mirroring the "ding" endpoint,
then points the speaker at that local URL.
The design is a pluggable Provider interface (pkg/service/tts) wrapping
two modes:
- translate: hands the speaker the (undocumented) Google Translate URL
directly (no credentials), reusing models.BuildTranslateTTSURL.
- google-cloud: REST API key auth (no SDK/gRPC), bytes cached locally.
Surfaces:
- service: POST /mgmt/tts/speak, GET /mgmt/tts/config, GET /media/tts/{id};
configured via TTS_PROVIDER / TTS_GOOGLE_API_KEY / TTS_LANGUAGE /
TTS_VOICE / TTS_APP_KEY / TTS_VOLUME.
- CLI: `soundtouch-cli tts speak` (calls the service with mgmt Basic Auth).
- web: a "TTS" source view (like Play URL / TuneIn), proxied to the
service via /api/device-speak/{id}.
The /speaker app_key requirement and model limitations still apply; see
docs/content/docs/reference/SPEAKER-ENDPOINT.md.

The `find` family runs the search inside the CLI, querying the radio
provider's public API directly (no speaker cloud, no soundtouch-service).
Make it the canonical path and deprecate the speaker-based search family.
- Add `find-tunein` and `find-radiobrowser` siblings; refactor the find
actions onto a shared `runFind` helper (all support `--more`).
- Rename the unreleased `search-radiobrowser` to `find-radiobrowser`.
- Deprecate `search`, `search-tunein`, `search-pandora`, `search-spotify`:
they keep working but print a stderr deprecation notice (new
`PrintDeprecation` helper) pointing at the `find*` replacement. Pandora
and Spotify have no built-in equivalent yet (they need the speaker +
account), so their notices say so.
- Docs: lead with the `find` family as recommended; mark the speaker-based
search commands deprecated; drop the misleading "service-side" wording
in favour of "built-in / queries the provider directly".
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add CLI-REFERENCE entries for the new service-side search commands
(`station find --provider tunein|radiobrowser [--more]` and
`station search-radiobrowser`), with a subsection explaining they run
the search in AfterTouch itself — working without the speaker's live
cloud and without a reachable --host. Also document the pre-existing
but undocumented `station list`.

Documents the iptables block that SoundTouch firmware (since 2018)
applies to traffic from other subnets, which prevents AfterTouch from
being reachable when the speaker and server are on different VLANs.
Two fixes: targeted ACCEPT rule (from spookie85, discussion #354) and
the simpler DROP-line comment-out (from dekiesel). Also notes the ST20
Series I outbound-port restriction on non-standard ports (gmuth).
Outgoing link kept to our own discussion #354 for attribution; the

Following user feedback (Lang, issue #432 thread) the docs guides now
contain all operational detail — installation, configuration, service
management, logs, updates, and removal — and the scripts READMEs become
thin pointers to the docs rather than the other way around.
RASPBERRY-PI.md: expanded to cover soundtouch-web alongside
soundtouch-service (install, config, port-conflict note, service
management, logs, update, removal, arch auto-detection, security).
scripts/raspberry-pi/README.md: trimmed to a quick-start with the two
one-liners plus a link to the docs guide.
EXTERNAL-HOST-WALKTHROUGH.md Step 7: replaces the vague "download from
Releases" note with the actual install-web.sh one-liner and a link to
RASPBERRY-PI.md#soundtouch-web; adds a non-Pi install option too.
ON-DEVICE-INSTALL-WALKTHROUGH.md: removed both back-references to
scripts/on-device-install/README.md; added self-contained sections for
Updating (with rollback tip), Service management, Logs, and Uninstalling
so the walkthrough is complete without leaving the docs.

Hextra's production build bundles assets/css/custom.css into
css/compiled/main.css. The original '../fonts/' relative path resolved
correctly from css/custom.css (dev) but landed at css/fonts/ in
production — one directory too deep.
Fix: use '../../fonts/' so the URL resolves correctly from every
output location browsers may encounter:
dev: /css/custom.css → ../../fonts/ → /fonts/
production: /css/compiled/main.css → ../../fonts/ → /fonts/
GH Pages: /Bose-SoundTouch/css/compiled/main.css
→ ../../fonts/ → /Bose-SoundTouch/fonts/
Browsers clamp traversal at the origin root, so going two levels up
from /css/custom.css still reaches /fonts/ — safe in dev, correct in
production.

EXTERNAL-HOST-WALKTHROUGH.md — Step 7 "Via soundtouch-web":
Replaced the single save path with two labelled options:
- ★ Star button: appears in the Now Playing card's top-right corner,
opens a slot picker (1–6), turns gold once mapped.
- + button: appears on each preset tile on hover, saves directly to
that slot without a picker.
Added a one-liner on when to use each.
PRESET-QUICKSTART.md:
New "Via soundtouch-web (browser UI)" section added above the CLI
section, covering both the ★ star and + paths with step-by-step
instructions.
soundtouch-web-roadmap.md:
- Added a "Shipped" callout noting that preset-slot saving is done.
- Retitled the Favorites section to "Favorites (device-native, distinct
from presets)" and added a note clarifying it refers to the speaker's
/favorites API (different from the 6 preset slots) which is still
pending.

Stripping the .md extension alone is not enough under Hugo pretty URLs.
A page rendered at /guides/DEPLOYMENT-OVERVIEW/ treats a bare relative
href like 'CLOUD-DEPLOY-WALKTHROUGH' as relative to that directory,
producing /guides/DEPLOYMENT-OVERVIEW/CLOUD-DEPLOY-WALKTHROUGH (404).
Switch to site.GetPage to look up the target page by its content path
(resolved relative to the current file's directory) and write its
RelPermalink into the href. This gives an absolute path that is correct
in both the dev server and the GitHub Pages build (where --baseURL
injects the /Bose-SoundTouch/ prefix via RelPermalink automatically).
Also handles anchored links (OTHER.md#section) and falls back to
bare-stripped path when GetPage finds no match.

The hextra/hero-button and hextra/feature-card shortcodes call
Hugo's relURL on any link starting with '/'. relURL prepends the
baseURL sub-path — but the deployed site was producing /docs/...
instead of /Bose-SoundTouch/docs/..., meaning relURL was seeing
a baseURL with no sub-path (likely just the domain).
Rather than depend on relURL working correctly at build time,
remove the leading slash from all four internal links. Bare paths
are emitted verbatim by the shortcode and are resolved by the
browser relative to the page's own URL (/Bose-SoundTouch/ on
GitHub Pages, / on local dev) — correct in both environments.

actions/configure-pages v5+ exports HUGO_BASEURL automatically,

while local dev (docker-compose.docs.yml already passes --baseURL /)
continues to work unchanged.
Also change hugo.toml baseURL to '/' as the neutral local default.

Bose shut down SoundTouch cloud services on 2026-05-06. Update the three
main user-facing docs to reflect that the shutdown has happened:
- README.md: rename section, rewrite opening paragraph, reframe the two
getting-started scenarios as 'already migrated' vs 'starting fresh'.
- SURVIVAL-GUIDE.md: past-tense title and opening; remove duplicate
Scenario B heading (copy-paste leftover from earlier edit); remove the
table of redirect methods and TLS note that belonged to the deleted
pre-shutdown Scenario B stub.
- MIGRATION-GUIDE.md: remove the 'cloud is still running' note from the
Sync step; fix the post-migration backup blurb to reference
soundtouch-backup rather than a non-existent Step 4 tar.gz.

Data Sync requires AfterTouch to reach the speaker outbound, which
fails when AfterTouch is running in the cloud. Replace with the
correct three-step workaround from wimdeblauwe (discussion #295):
1. Manually create Sources.xml in the server's data volume with the
default source set (AUX, LOCAL_INTERNET_RADIO, TUNEIN, RADIO_BROWSER)
2. Send a sourcesUpdated notification to the speaker from a local machine
3. Power-cycle the speaker (CLI reboot is insufficient; firmware only
activates new source types at boot)
Add a clear note that Data Sync is not available from cloud deployments.

'Each speaker needs its own install' is only true when the firmware
binds port 8000 to loopback (older devices, issue #196). Devices that
expose the port on the LAN can run one on-device AfterTouch and point
other LAN speakers at it — same as a Raspberry Pi. Qualify the cell
accordingly.

Problem: the existing docs gave no clear path for non-technical users.
- GETTING-STARTED.md is a Go library developer guide
- RASPBERRY-PI.md stops after the service is running (no migration or preset steps)

The markdown-link-check CI step caught five stale links in
docs/README.md's Concept Documentation section pointing at files
the previous commit moved into docs/archive/. Replaced with a
pointer to SUMMARY.md's Concepts section + a short curated list
of the currently-relevant docs (Spotify Overview, Spotify OAuth,
Amazon Music OAuth, Encrypted Export, Request Recording). The
archived planning artefacts get a single line acknowledging
their existence under docs/archive/.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The speaker firmware constructs the OAuth host by appending "oauth" to
the first label of the configured streaming hostname (aftertouch.lan
→ aftertouchoauth.lan, used by both Spotify and Amazon Music token
refresh). AfterTouch's DNS server previously only hijacked the
hardcoded list of Bose hostnames, so operators self-hosting at a
custom hostname had to add the OAuth alias themselves — and the
amazon-music-oauth.md / spotify-overview.md docs incorrectly
claimed the DNS server handled it automatically.
ofthesun9 (#337) caught this via the worst variant: IP-based
serverURL (192.168.0.30 → 192oauth.168.0.30), which is a malformed
hostname no DNS resolver can answer for. There is no clean DNS
workaround for the IP case — the operator must use a hostname.
Three changes:
- pkg/discovery/dns.go DeriveOAuthHostnames parses the configured
serverURL, derives <first-label>oauth.<rest> when the host is a
hostname (not IP), and adds it to the DNSDiscovery hijack list. IP
serverURLs deliberately yield no derivation — the malformed name
isn't worth handling and the new health check surfaces the trap.
- New checks_oauth_target health check fires a Warning when serverURL
is an IP literal, with a concrete example of the malformed name
(`192oauth.168.0.30`) and a ManualCommand pointing at the switch.
- amazon-music-oauth.md and spotify-overview.md rewritten: drop the
false "automatic" claim, document the three resolution paths
(AfterTouch DNS + speaker resolves via it / external LAN DNS /
per-speaker /etc/hosts), and explicitly flag IP-based --server-url
as incompatible with OAuth on either provider.
Tests cover the derivation matrix (hostname / IPv4 / IPv6 / single
label / empty / garbage URL), shouldIntercept's new behaviour
(derived host hit, base host not auto-hijacked, case-insensitive),
the health check's four states, and the malformed-host helper.
