1. A first playback device comprising:
a communications interface;
one or more processors;
an audio amplifier; and
at least one non-transitory computer-readable medium comprising program instructions that are executable by the one or more processors such that the first playback device is configured to:
operate in a first mode, wherein the audio amplifier consumes less power while the first playback device is in the first mode than in a second mode;
while operating in the first mode, receive, via the communications interface, a first wake-up packet;
based on receiving the first wake-up packet, exit the first mode and enter the second mode, wherein the program instructions that are executable by the one or more processors such that the first playback device is configured to enter the second mode comprise program instructions that are executable by the one or more processors such that the first playback device is configured to enable the audio amplifier of the first playback device;
while operating in the second mode, (i) receive, via the communications interface, an audio stream comprising audio content, (ii) cause a second wake-up packet to be sent to a second playback device and thereby cause the second playback device to exit a respective first mode and enter a respective second mode, wherein a respective audio amplifier of the second playback device consumes less power while the second playback device is in the first mode than in the second mode, (iii) begin forwarding, via the communications interface, the audio content to the second playback device, and (iv) play back, via the audio amplifier, the audio content in synchrony with the second playback device;
cease forwarding the audio content to the second playback device; and
after the cessation of forwarding the audio content to the second playback device, exit the second mode and enter the first mode.
