Systems and methods for audio output control are disclosed. Audio may be output via a speaker of a communal device associated with a first portion of an environment. A user may provide a user utterance indicating an intent to add another device in a second portion of the environment to the audio-output session, and/or an intent to move the audio-output session from the first device to the second device, and/or an intent to remove a device from an audio-output session. Based on this determined intent, audio-session queues may be associated and dissociated from devices and device states may be altered to effectuate the intent of the user utterance.

Audio output control

Multiple processes of an application (or multiple applications capable of sharing private data) of a mobile device can communicate in a process-safe, secure, and efficient manner via a shared private file system. A first process can produce shared data for a second process to consume via the file system. For example, when the shared data changes, the first process can write a new file to the private file system and rename the new file to a specified file name. When the second process needs the shared data, the second process can evaluate certain metadata of the new file, such as a timestamp or a field comprising a monotonically increasing number. If a stored metadata value associated with the specified file name is less than the metadata value of the new file, the second process can safely retrieve the shared data from the new file.
