Abstract
Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of testing a system-on-chip (SoC). The method includes generating data for a plurality of audio channels. The data comprises first data corresponding to a first audio channel and second data corresponding to a second audio channel. The method further includes outputting the first audio channel over a first output port of the SoC for output by a speaker. The method further includes outputting the second audio channel over a second output port. The method further includes looping back the second audio channel from the second output port to a first input port of the SoC as third data. The method further includes comparing the third data to the second data. The method further includes determining if the SoC is operating correctly based on the comparison of the third data to the second data.
