A device and method are provided for merging one or more secondary audio channels, received from either a streaming application or from memory, with a primary stream of audio data output from a main audio decoder. In addition to the audio decoder, the device/method employs a controller for processing received secondary audio data in a streaming application, and retrieving from system memory audio PCM data once stored. An audio playback device is provided for formatting the PCM data for mixing with the primary stream of audio data output from the audio decoder. Multiple digital-to-analog converters convert the multiple streams of audio data into analog signals which are then mixed into a single merged audio signal for presentation.
