Abstract: Embodiments are provided for intelligently activating an amplifier in a playback device based on proximity detection. The playback device may be in a quasi-idle state when the playback device is not rendering media content. The quasi-idle state of the playback device may involve an amplifier in the playback device being inactive, while some other components or modules of the playback devices remain active. The playback device may include a proximity sensor configured to detect movement relative to the playback device. If movement is detected indicating that a user input to cause the playback device to render media content is anticipated, the amplifier may be pre-emptively activated such that the playback device enters an active state from the quasi-idle state. In some cases, the playback device may send a message to one or more other playback devices to cause the other playback devices to enter an active state.

Abstract: An example computing device is configured to transmit playback preference tracking information to a media service registered with a media playback system and, after transmitting the playback preference information, (a) determine a first time boundary corresponding to a beginning of a zone scene that causes a first playback device in a first zone of the media playback system to be configured for synchronous playback of media with a second playback device in a second zone of the media playback system, (b) determine a second time boundary corresponding to an end of the zone scene, and (c) transmit, to the media service registered with the media playback system, a request to remove playback preference tracking information received between the first time boundary and the second time boundary.

Abstract: Embodiments described herein involve an auxiliary zone contributing audio to a primary zone. In an example implementation, a network media system determines that a first zone in the network media system is playing back a first type of audio content and that a second zone in the network media system is not playing back audio content. While the first zone is playing back the first type of audio content and the second zone is not playing back audio content, the network media system forms a temporarily playback configuration. In the temporary playback configuration, the first zone plays back primary audio content including full frequency range audio content and the second playback device of the second zone plays back auxiliary audio content including low frequency range audio content.

Abstract: Techniques for auditioning audio content by a playback device involve (1) receiving, via at least one communication interface of the playback device, first audio content to be played back by the playback device, (2) playing back the first audio content, (3) while playing back the first audio content, receiving, via at least one microphone of the playback device, second audio content to be played back by the playback device (4) after receiving the second audio content: (i) suspending playback of the first audio content; and (ii) playing back the second audio content, and (5) after playing back the second audio content, resuming playing back the first audio content.

Abstract: Example techniques describe may facilitate a playback device applying a determined audio setting. An example implementation involves a first playback device receiving, over an unsecure network, a message indicating that a second playback device is available to join a playback network, wherein the first playback device is connected to the playback network. Based on a pre-existing configuration table, the first playback device determines an audio setting corresponding to a playback configuration for the second playback device, the playback configuration including the second playback device playing back audio synchronously with the first playback device in the playback network. The first playback device transmits, to the second playback device, one or more messages instructing the second playback device to apply the determined audio setting upon joining the playback network.

Abstract: A first playback is configured to (i) while connected to a local data network via a network interface using a first wireless networking protocol, receive a command to begin communicating with a second playback device in a group of playback devices for synchronous playback, (ii) based on the received command, begin communicating with the second playback device, (iii) determine that the second playback device is connected to the local data network using a second wireless networking protocol, (iv) based the determining, cause the second playback device to operate as a group coordinator of the group of playback devices, wherein the group coordinator (a) receives audio content from an audio source, and (b) transmits the audio content to the first playback device during rendering of the audio content by the group of playback devices, and (v) thereafter, receive the audio content from the second playback device.

Abstract: A muffler for an exhaust gas system of an internal combustion engine. The muffler has a muffler housing having at least two interconnected housing shells delimiting a muffler interior. Each housing shell has a connecting edge extending away from the muffler interior. The housing shells are mutually connected by material bonding in the region of their mutually adjacent housing shell connecting edges. An insulating arrangement covers at least regions of the inner side of one of the housing shells. The insulating arrangement has an insulating shell with an insulating shell connecting edge extending away from the muffler interior and the insulating shell is arranged with the insulating shell connecting edge between the mutually adjacent connecting edges of the housing shells and is connected by material bonding to the connecting edges of the housing shells in the region of the insulating shell connecting edge.
