Embodiments are provided for satellite volume control. An example method includes receiving an input at a playback device to adjust a volume for a plurality of playback devices that are grouped for synchronous playback of audio content, wherein the plurality of playback devices includes the playback device. The method also includes sending a first message over a network from the playback device to a device associated with the plurality of playback devices, the first message including information based on the input, wherein the information is used to adjust the volume of the plurality of playback devices. The method also includes receiving a second message at the playback device over the network, the second message including information for the volume of the playback device, wherein the volume is based on the adjusted volume of the plurality of playback devices.

A muffling device includes an acquisition circuit, configured to obtain reference sound wave information of a user. The muffling device includes a modulation circuit, configured to analyze an acoustic wave characteristic of the reference sound wave information to obtain a characteristic parameter of the reference sound wave information. The muffling device includes a muffling circuit, configured to generate compensated sound wave information according to the characteristic parameter of the reference sound wave information. The muffling device includes a correction circuit, configured to compare muffed sound wave information superimposed by the compensated sound wave information and the reference sound wave information with the reference sound wave information, and feed back a comparison result to the muffling circuit. The muffling circuit can adjust the compensated sound wave information according to a fed back comparison result. The muffling device includes an output circuit, configured to output adjusted compensated sound wave information.

An example computing system that maintains a playlist of media items for playback by one or more playback devices receives, from a first playback device, a request to play back the playlist and first operational data and also receives, from a second playback device, a request to play back the playlist and second operational data. The computing system provides the media items in the playlist to the first and second playback devices for substantially synchronous playback and, based on the first and second operational data, determines respective first and second advertisements. The computing system provides the first advertisement to the first playback device for playback during a given time slot designated for advertisements, and also provides the second advertisement to the second playback device for playback during the given time slot, such that the second playback device plays the second advertisement while the first playback device plays the first advertisement.

A computing device capable of controlling a networked media playback system receives data identifying a first zone player, a second zone player, and a zone scene including a predefined grouping of zone players including at least the first zone player and the second zone player. The computing device displays a representation of available zone players in the networked media playback system including a first selectable indication of the first zone player, a second selectable indication of the second zone player, and a third selectable indication of the zone scene that, when selected, causes the zone scene to be invoked such that the predefined grouping of zone players becomes configured for synchronous playback of media. While displaying the representation, the computing device receives a user input indicating that the zone scene has been selected to be invoked. Based on the user input, the computing device causes the zone scene to be invoked.
