ABSTRACT:
A method may include sampling a receive frequency at which information received over a communication link is played. The method may also include sampling a system frequency related to the communication link and computing a first value based on the sampled receive frequency and the sampled system frequency. A second value may be received via the communication link. The receive frequency may be adjusted based on the first value and the second value.
