Abstract
Systems and methods may provide for using audio output device driver logic to maintain one or more states of an audio accelerator in a memory store, detect a suspend event, and deactivate the audio accelerator in response to the suspend event. In addition, firmware logic of the audio accelerator may be used to detect a resume event with respect to the audio output accelerator, and retrieve one or more states of the audio accelerator directly from the memory store in response to the resume. Thus, the retrieval of the one or more states can bypass the driver logic.
