Abstract
Example apparatus disclosed herein compare one or more audio latency characteristics with one or more audio latency requirements in response to detection of an audio silence event, the audio latency characteristic(s) associated with at least one of a hardware layer or a device layer of an audio stack of a compute device, the audio latency requirement(s) associated with an application. Disclosed example apparatus also control a device layer of the audio stack to enter a device layer low power mode in response to a first determination that the audio latency requirement(s) is/are met by the audio latency characteristic(s). Disclosed example apparatus further control a hardware layer of the audio stack to enter a hardware layer low power mode in response to the first determination and a second determination that an operation condition for entry into the hardware layer low power mode is met.
