Abstract: While a first playback device is a member of a synchronous media playback group with a second playback device using a first media playback protocol, and after a particular playback setting is enabled using the first media playback protocol, the first playback device receives, from a media source device, a first media stream using a second media playback protocol. The first and second media playback protocols are incompatible. The first playback device determines that the particular playback setting is enabled and that the synchronous media playback group includes the first playback device and the second playback device. Subsequently, the first playback device (i) generates a second media stream based on the received first media stream, the second media stream including information for synchronous playback with the first playback device, and (ii) transmits, to the second playback device, the second media stream using the second media playback protocol.

While displaying the representations, the device receives, from a server, data indicating updated information associated with the plurality of households; and, in response, updates the graphical display to display at least an updated representation of media being played by the selected zone.

Abstract: Example techniques relate to a loss of control of a playback queue. An example implementation involves a playback device receiving, from a native controller, an instruction to add audio tracks to a queue, where, in a first mode associated with the native controller, the playback device is configured to play back from the queue. While the audio tracks are in the queue, the playback device receives, from a media player application associated with a particular wireless protocol, an instruction to play back a media item. In response, the playback device is configured to play back in a second mode associated with the particular wireless protocol, where, in the second mode, the queue is not in use. While playing back the media item, the playback device detects a loss of control by the media player application and configures the playback device to play back in the first mode.

Abstract: Example techniques relate to a playback device that facilitates queue identification. In an example implementation, a playback device receives, from a first controller, instructions representing a command to populate a playback queue with one or more first media items; the instructions are associated with a first application identifier corresponding to the first controller. Based on the received instructions, the playback device populates the playback queue with the one or more first media items and forms an association between the playback queue and the first application identifier. The playback device receives, from a second controller, instructions representing one or more first commands to access the playback queue; the instructions are associated with a second application identifier corresponding to the second controller.

Abstract: Example techniques involve identification of device groups. In an example implementation, a mobile device displays, via a control application, a synchrony group control including controls to select playback devices for a synchrony group. The mobile device receives input data representing a command to create a new synchrony group, the input data including input data representing selection of two or more playback devices for a new synchrony group. In response, the mobile device forms the synchrony group by receiving input data indicating a particular group identification for the new synchrony group, determining that the particular group identification is unique among other synchrony groups, and sending data representing instructions to the playback devices to form the new synchrony group with the particular group identification. In response to forming the new synchrony group, the mobile device updates an interface for the media playback system to indicate the new synchrony group.

Abstract: Example systems and techniques disclosed herein facilitate interoperability between different media playback systems referred to herein as a virtual line-in (VLI) media playback system and a native playback system. When a VLI session is created by a VLI sender, a first native playback device can join a VLI group as a VLI receiver. As a VLI receiver, the first native playback device receives audio content and playback commands from the VLI sender to facilitate synchronous playback with other VLI receivers. At the same time, this native playback device can concurrently operate as a native domain group coordinator of a native domain synchrony group. As the native domain group coordinator, the native playback device translates VLI domain audio, control, and timing signals into the native domain and distributes such signals to native domain group members. In this way, the native domain group members can synchronize their playback with the VLI group.

Abstract: Embodiments described herein may involve queue versioning. An example implementation may involve a playback device initiating playback of a queue including one or more first audio streams. A queue identification token stored in data storage represents a current version of the queue. The playback device receives, from a computing system, data representing instructions to add one or more second audio streams to the queue, the instructions including an indication of the one or more second audio streams and a first token representing an expected queue version. The playback device determines whether the expected queue version represented by the first token matches the current version of the queue represented by the queue identification token. If not, the playback device foregoes adding the one or more second audio streams to the queue.

Abstract: Example techniques relate to cloud queue tombstones. An example implementation may involve a computing system receiving instructions to remove a particular media item from a playback queue. Based on the instructions, the computing system removes the particular media item from the playback queue and adds, to the playback queue, a tombstone indicator indicating that the particular media item has been removed from the playback queue. The computing system receives, from the media playback system, a request for a window of one or more media items from the playback queue. Based on the request, the computing system sends, to the media playback system, data representing a particular window of media items from the playback queue, wherein the particular window includes the tombstone indicator. The computing system detects a given tombstone removal trigger from among multiple tombstone removal triggers and based on the detecting, removes the tombstone indicator from the playback queue.
