1. A playback device comprising:
- a capacitive proximity sensor;
a conductive speaker grille;
one or more processors; and
a data storage having stored therein instructions executable by the one or more processors to cause the playback device to perform operations comprising;
causing a grounding plane of the capacitive proximity sensor to be coupled to the conductive speaker grille;
determining that the playback device will be rendering audio; and
responsively causing the grounding plane of the capacitive proximity sensor to be decoupled from the conductive speaker grille while the playback device is rendering audio.

Abstract
An example embodiment includes a playback device that includes a capacitive proximity sensor; one or more speakers; a conductive speaker grille; and a control system that decouples a grounding plane of the capacitive proximity sensor from the conductive speaker grille while the one or more speakers are rendering audio and couples the grounding plane of the capacitive proximity sensor to the conductive speaker grille while the one or more speakers are not rendering audio.
