Techniques for controlling one or more audio amplifiers in or associated with a device coupled on a local area network are disclosed. An example playback device includes a processor, an amplifier, a network interface, and a memory. The memory includes a software module that, when executed by the processor, causes the playback device to: operate in a first power mode in which the amplifier consumes a first amount of power; while operating in the first power mode, determine that a defined time has passed since receiving, via the network interface, a specified type of data packet; and based on determining that the defined time has passed since receiving the specified type of data packet, transition from operating in the first power mode to operate in a second power mode in which the amplifier consumes a second amount of power, wherein the first amount of power is greater than the second amount of power.
A first playback device comprising an amplifier, wherein the first playback device is configured to, after the first playback device has determined that a defined time has passed since receiving a packet addressed to the first playback device and comprising audio data, transition the first playback device from (i) operating in a first power mode where the amplifier consumes a first amount of power to (ii) operating in a second power mode where the amplifier consumes a second amount of power that is less than the first amount of power.
Tangible, non-transitory computer readable media comprising instructions encoded therein, wherein the instructions, when executed, cause a first playback device to perform functions comprising:
