Abstract
A method of generating asynchronous feedback information for asynchronous, isochronous audio communication may include determining a relative change of stored samples in a device and generating the asynchronous feedback information provided to a host from the device based on the relative change. A method of generating asynchronous feedback information for asynchronous, isochronous audio communication may include determining a relative phase of a host clock for a host and a device clock for a device and generating the asynchronous feedback information provided to the host from the device based on the relative phase.
