    Abstract: A method performed by a first electronic device that is communicatively coupled to a wireless headset, the method includes, while engaged in a call with a second electronic device, communicating with the wireless headset via a bi-directional wireless audio connection; determining that a joint media playback session has been initiated in which the first and second electronic devices are to independently stream media content for separate playback by both of the first and second electronic devices while engaging in the call; and switching to communicate with the wireless headset via a uni-directional wireless audio connection based on a determination of one or more capabilities of the wireless headset, wherein a mix of 1) one or more signals associated with the call and 2) an audio signal of the media content is transmitted to the wireless headset over the uni-directional wireless audio connection.

    Abstract: A method performed by an audio source device. The method receives a first audio signal and a second, different audio signal and encodes the first audio signal and the second audio signal, wherein the first audio signal is encoded differently than the second audio signal. The method generates a first data packet that comprises the first encoded audio signal and a first volume level and a second data packet that comprises the second encoded audio signal and a second volume level, wherein the first volume level is lower than the second volume level and transmits, over a wireless connection, the first and second data packets as a dual audio stream to an audio output device.

    Abstract: A host device communicating with a plurality of accessory devices transmits audio data packets via a broadcast channel to the plurality of accessory devices. When one of the plurality of accessory devices determines an audio data packet has not been received, the accessory device sends a negative-acknowledgement signal (NACK) via a unicast channel. The NACK indicates that the at least one of the accessory devices did not receive at least one audio data packet. The host device retransmits the at least one audio data packet indicated as not being received via the broadcast channel to the plurality of accessory devices. Other aspects are also described and claimed.

    Abstract: A device may store a plurality of different coexistence profiles for different possible communication scenarios. The device may be initialized with a first one of the coexistence profiles, and may operate to dynamically switch to different ones of the coexistence profiles based on current conditions. Each coexistence profile may include a number of coexistence related parameters stored as a plurality of data structures. During device use, the device may dynamically select an appropriate coexistence profile based on the current communication conditions, such as Wi-Fi RSSI, Bluetooth RSSI, and/or the number of Wi-Fi and/or Bluetooth devices with which communication is currently occurring, among other possible factors. The coexistence profile is selected to provide the best possible Wi-Fi and/or Bluetooth output performance based on current conditions. The device may repeatedly dynamically select different coexistence profiles as conditions change, e.g., may select different coexistence profiles on a second or even millisecond basis.

    Abstract: Techniques for routing communication to a common audio output device connected multiple audio signal source devices are disclosed. For each of audio signal source devices, a set of inputs are assessed. The set of inputs can include: an operational state of the audio signal source device, an interaction with the audio signal source device, an audio-producing application being executed by the audio signal source device, or a degree of user interaction with the audio-producing application. At a point in time, an audio routing score is generated for each of the audio signal source devices according to a weighted calculation of the set of inputs based on the assessing. Finally, an audio signal routing decision is made, to route an audio signal from one of the audio signal source devices to the audio output device, based on the audio routing score for each of the audio signal source devices.

    Abstract: A source device can transmit initial streaming content to a playback device (e.g., wireless ear buds) using first settings and measure playback performance of the content at a plurality of times. The measured performance values can relate to a quality of communication of the initial streaming content between the source device and the playback device, e.g., relating to packet loss, retransmission rates and patterns, fluctuations in a playback (jitter) buffer, and/or other values. The measured performance values can be used to determine one or more second settings to be used for a playback of subsequent streaming content between the source device and the playback device. In this manner, each source device can account for variations in communication behavior specific to a user (e.g., due to differences in body type as electromagnetic waves travel through the body when a source device is in a pocket).
