Embodiments are described herein that provide a dedicated command device that is bonded to a zone player or zone to perform adjustments to the zone player or zone. In an example implementation, a command device receives an instruction to pair with a first playback device that is associated with a group of playback devices that includes the first playback device and at least one additional playback device. The group of playback devices is associated with at least one group variable controlling playback by the playback devices of the group. The command device receives an input to adjust a first group variable of the at least one group variable and transmits, via a wireless communications interface, a command that causes an adjustment of the first group variable for the group of playback devices.

Embodiments described herein provide for detecting presence of an object in proximity to a playback device and responsively performing one or more operations. In an example implementation, a playback device detects, via a proximity detector of the playback device, presence of an object in proximity to the playback device. In response to detecting the presence of the object, the playback device performs one or more operations.

An audio device includes an amplifier having a volume control circuit, a communication circuit configured to communicate with a host apparatus, a processor, and a memory having stored thereon instructions executable by the processor to cause the audio device to perform: setting a volume value in the volume control circuit; receiving, from the host apparatus through the communication circuit, an instruction value indicating a volume value to be set in the volume control circuit; comparing the received instruction value with a set value that is a volume value set in the volume control circuit; and sending an instruction signal based on a comparison result to the host apparatus through the communication circuit.

Disclosed are a volume adjusting device and an adjusting method thereof for enabling an electronic device such as a TV to perform a volume adjustment operation among operations executable by the electronic device according to a prediction model stored through machine learning based on communication with surrounding devices in a 5G communication environment. According to the present disclosure, when information indicating adjustment of the volume of an electronic device by a user is generated, volume adjustment information may be learned, and the volume may be automatically adjusted to a volume preferred by the user on the basis of the learned information when the user views a video on the electronic device.
