1. A method for operating a wireless speaker device, comprising:
determining a host device is in a state, wherein the speaker device is in a wake state, and the host device is communicatively coupled with the speaker device in a peer-to-peer wireless network;
sending one or more packets to the host device;
determining the host device is in an inactive state when there is no response packet received from the host device;
entering, in response to the determination that the host device is in the inactive state, a standby state;
enabling, in response to the entering the standby state, a communication circuit of the speaker device to be in a second state of the communication circuit different from a first state of the communication circuit, wherein the second state of the communication circuit consumes less power than the first state of the communication circuit; and
enabling, in response to the entering the standby state, an audio processing circuit of the speaker device to be in a second state of the audio processing circuit different from a first state of the audio processing circuit, wherein the second state of the audio processing circuit consumes less power than the first state of the audio processing circuit.
