1. A system comprising a first native playback device configured as a first Virtual Line-In (VLI) receiver of a VLI group, wherein the VLI group is configured to (i) receive, via an input interface of a first VLI device configured as a VLI sender of the VLI group, user input to perform a mute operation, the mute operation corresponding to a first VLI domain mute command to set volume level to a pre-defined inaudible volume level and (ii) send, via a network interface of the first VLI device, the first VLI domain mute command, and wherein the first native playback device is configured to perform functions as the first VLI receiver of the VLI group, the functions comprising:

  • receiving, via a network interface of the first native playback device, the first VLI domain mute command;

    translating the first VLI domain mute command to one or more corresponding first native domain mute commands, wherein the one or more corresponding first native domain mute commands comprise;

    (i) enabling a native domain mute state on the first native playback device, (ii) storing a current native domain volume level of the first native playback device, and (iii) setting the native domain volume level to zero; and

    in response to receiving the first VLI domain mute command, carrying out the one or more corresponding first native domain mute commands to perform the mute operation on the first VLI receiver.
