An example apparatus includes a network interface configured to receive audio content over a playback network. A processor comprising instructions which when executed, cause the processor to detect that a portable playback device has joined the playback network. The processor is to update a state variable to indicate that the portable playback device has joined the playback network. The processor is to play audio content received over the playback network based on the state variable. The processor is to detect that the portable playback device is not joined to the playback network. The processor is to, after detecting that the portable playback device is not joined to the playback network, update the state variable to indicate that the portable playback device is not joined to the playback network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Portable playback device state variable","description":"Systems, methods, apparatus, and articles of manufacture to facilitate playback of multimedia content are disclosed.
