Abstract

Methods and systems are provided for volume interactions for connected playback devices. In an example implementation, a first playback device applies a state variable update associated with a group of playback devices comprising the first playback device and one or more second playback devices. The state variable update indicates a limited volume range associated with the first playback device. The first playback device renders audio content in synchrony with the one or more second playback devices. Rendering the audio content involves a subwoofer speaker of the first playback device rendering a bass frequency component of the audio content. The first playback device receives input data indicating a group volume adjustment for the group of playback devices and adjusting a playback volume of the first playback device based on the group volume adjustment and the limited volume range.
