A set of user pools can be determined based on location data associated with each device in an audio/video (A/V) conference. A key active user can be determined for each user pool of the set of user pools based on valid audio signals received from each device within each user pool. A determination can be made whether there is feedback within each user pool. Responsive to determining feedback in at least one user pool, speakers of devices within the at least one user pool can be disconnected except for the key active user device within each respective user pool.

A terminal for outputting multi-channel audio using a plurality of audio devices, the terminal can include a camera; a communication interface configured to communicate with a plurality of first audio devices; and a processor configured to receive device information about the plurality of first audio devices through the communication interface or the camera; configure a multi-channel audio system including at least two second audio devices selected from among the plurality of first audio devices based on the device information; and output audio data through the at least two second audio devices based on audio system information corresponding to the multi-channel audio system.

An example implementation may involve a group of wearable playback devices including a first wearable playback device and a second wearable playback device. The wearable playback devices render multi-channel audio content according to particular playback responsibilities in the group. When a failure or other issue with the second wearable playback device occurs, the first playback device assumes at least part of the playback responsibility of the second playback device.

An apparatus, electronic device, method and computer program wherein the apparatus comprises: processing circuitry; and memory circuitry including computer program code, the memory circuitry and the computer program code configured to, with the processing circuitry, enable the apparatus to: detect an audio module connected to the apparatus wherein the audio module comprises a user replaceable module; determine one or more parameters of the audio module; and enable the processing of the signals used for the audio module in accordance with the determined one or more parameters.

Example techniques may involve headphone interaction. An implementation may include while headphones are disconnected from a control device, the control device receiving an indication of particular audio content being played back by a first zone of the media playback system. While the particular audio content is being played back by the one or more playback devices of the media playback system, detecting that headphones have been connected to the first control device. Headphones may be connectable to the control device via either (a) an analog headphone jack or (b) a point-to-point personal area network connection. In response to detecting that the headphones are connected to the control device: the control device (i) causing the one or more playback devices of the first zone to stop playback of the particular audio content; (ii) retrieving the particular audio content and (iii) resuming playback of the particular audio content via the connected headphones.

Systems, methods, and non-transitory computer-readable storage media for performing a role swapping operation between a pair of non-tethered wireless ear buds after detecting a triggering event. Further, state information can be coordinated between devices, including in connection with performing a role swap between buds in a pair of wireless, untethered ear buds, where one wireless ear bud is in a primary role and is responsible for a connection with a companion device, and another wireless ear bud in the pair is in a secondary role.

Provided are an MIC switching apparatus and an MIC switching method for a vehicle, which can achieve automatic switching between a headset MIC and an on-board device MIC. The MIC switching apparatus includes: a wireless headset MIC (14), a connector (12), an on-board device MIC (24), a data selector (13), and a controller (11). The connector (11) is configured to, when receiving a connection signal, control the data selector (13) to receive a sound signal from the on-board device MIC (24), and when not receiving the connection signal, control the data selector (13) to receive a sound signal from the wireless headset MIC (14). With the above features, automatic switching from sound acquisition by the on-board device MIC to sound acquisition by the wireless headset MIC may be achieved, thereby improving user experiences and increasing market competitiveness of the vehicle applying the method.

An earphone-switching method in a mobile terminal are disclosed. The mobile terminal is currently connected with a first earphone, and the method includes performing an earphone-switching operation in response to the mobile terminal being in a call state and an earphone-switching condition being met, the earphone-switching operation being configured for switching the first earphone to a second earphone; detecting whether at least one of a first voice data and a second voice data is obtained during the earphone-switching operation; and sending the at least one of the first voice data and the second voice data, in response to the at least one of the first voice data and the second voice data being obtained, wherein the first voice data is sent to the second earphone, and the second voice data is sent to the peer terminal.

A system and method for routing the audio output from a selected one of a plurality of independent audio sources to an audio system for amplification/playback; the routing being based upon the movement of a user's head, and in particular the user's line-of-sight inferred from the movement. The invention employs a spatial mapping of the plurality of audio sources and routes the respective audio output of each of the sources to the audio amplification/playback system upon making the determination that the user's line-of-sight is being directed to a particular one of the audio sources.

The present application discloses playback devices and networks, software for operating playback devices and playback device networks, and methods of operating playback devices and networks, where an individual network device is configured to switch between operating various operating modes comprising a non-paired mode and a paired mode, where the playback device is configured to output various channels of audio content within various audio frequency ranges while operating in the various operating modes.
