Tapping a speaker in the group list could do nothing at all: Home Assistant answers media_player.join with a 200 before the membership is live, and Music Assistant drops a join it cannot act on without reporting anything. The single confirming reload could not tell "not applied yet" from "never applied", so the tap looked like it worked.

What changed

  • confirmGroupChange reloads the speakers up to three times after a join/unjoin and only then decides. A change that never lands raises the existing error banner instead of passing silently.
  • MediaPlayerEntity decodes active_queue and exposes isPlayingExternalSource — live audio with no Music Assistant queue behind it.
  • When a join fails and the leader is on such a source, the banner names it: "Köket spelar från en annan app. Starta musiken härifrån för att spela på flera högtalare". That is the common case — a Sonos playing Spotify Connect has no MA stream to extend to a second speaker — and starting playback from the app fixes it.
  • The wait between confirmation reloads is injected, so tests confirm instantly rather than on wall time.

Verified against the live instance

media_player.join with Kitchen (Sonos) as leader and Spa (AirPlay) as member returns [] with nothing in the system log while Kitchen streams Spotify Connect, and works within seconds once Kitchen plays a Music Assistant queue.

Tests

MusicViewModelGroupingRulesTests.swift covers both failure paths: a 200 that never applies, and a join onto an external source getting the explanatory banner. speakerJSON can stub active_queue, and the test class records banner messages as well as titles. Full suite passes (581 tests), SwiftLint clean.

Summary by CodeRabbit

  • New Features

    • Detects when speakers are playing audio from external sources, such as Spotify Connect, AirPlay, or TV.
    • Provides clearer messaging when grouping is unavailable because of external playback.
  • Bug Fixes

    • Grouping changes are now verified after joining or removing speakers.
    • Failed or unconfirmed grouping changes display an error message and clear pending status.
  • Tests

    • Added coverage for unconfirmed grouping changes and external-source playback errors.

Home Assistant answers media_player.join with a 200 before the membership is
live, and Music Assistant drops a join it can't act on without reporting
anything. The single confirming reload could not tell those apart, so a group
change that never happened looked like a successful tap.

Grouping now reloads up to three times before deciding, and raises the error
banner when the membership never changes. The usual cause is the leader playing
a source Music Assistant doesn't own — Spotify Connect straight to the Sonos
reports no active_queue — so MediaPlayerEntity decodes that attribute and the
banner names it, since starting playback from the app is the fix.

📝 Walkthrough

Walkthrough

MediaPlayerEntity now identifies playback from external sources. Grouping operations confirm membership through retries before completing. Tests cover unconfirmed joins and external playback failures, and the new test file is included in the Xcode test target.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 70f5b

Grouping feedback can remain stale when a speaker changes between Music Assistant and external playback, and a quick speaker selection change during confirmation could validate or explain the wrong group. The PR is mergeable with explicit owner awareness and follow-up on these bounded correctness risks.

Confirm the captured group leader.

confirmGroupChange calls isGrouped after suspension, so a changed activeSpeaker can make a successful join fail confirmation or make an unjoin pass against the wrong group. Pass the captured leader and member IDs, then check speakers[leaderID]?.groupMembers directly. Add a regression test that changes the selected speaker during waitBeforeGroupRecheck. Include screenshot evidence for the changed error-banner copy.

Assert the initial ungrouped state in both tests.

Each test only asserts state after reload() or after the grouping request. Assert that the speaker is initially ungrouped before the reload. This proves that failed grouping did not inherit existing membership.

As per coding guidelines, tests should validate both initial state and post-reload() state.

Confirmation called isGrouped, which reads whichever speaker is selected when
the reloads resume. Selecting another speaker mid-confirmation made a landed
join report failure, and could judge an unjoin against a group the request never
touched. Membership is now read from the leader the request was sent to, and the
external-source check reads that same leader.

Also compares activeQueueID in MediaPlayerEntity equality, which otherwise hides
a transition into or out of external playback from any future consumer.

Went through the review. Both correctness findings were real and are fixed in f03cd86.

Confirmation bound to the captured leaderconfirmGroupChange called isGrouped, which reads whichever speaker is selected when the awaits resume. It now takes the leader the request was sent to and reads speakers[leaderID]?.groupMembers directly; the external-source check reads that same leader instead of activeSpeaker. testJoinConfirmedAgainstTheLeaderItWasSentTo covers it: the confirmation-wait hook re-stubs the applied group and selects a different speaker mid-flight. Verified it fails against the old isGrouped implementation and passes with the fix, so it's pinning the actual behaviour.

activeQueueID in equality — added. No current consumer compares MediaPlayerEntity for change detection, so this was latent rather than a live bug, but the hand-written == lists every other stored property and omitting this one would trap the next reader.

Initial-state assertions — added to both tests.

Not doing: the screenshot of the error banner. It needs the app running against the live Home Assistant with a leader on an external source, and the repo has no snapshot or UI-test setup to capture it in CI. The banner copy is asserted verbatim in testJoinOntoAnExternalSourceExplainsWhyItFailed instead.

Full suite green (582 tests, 0 failures), SwiftLint clean.
