An integrated wireless audio unit (WAU) for a vehicle audio system is disclosed herein, that can take a plurality of audio streams as input, and output the audio streams to a plurality of output devices, where the output transmission is low latency (e.g., less than 15 ms end-to-end) and time-synchronous (e.g., with no float or drift in latency). The input streams may be received via various protocols in the digital or analog domain, and the WAU may mix, blend, and process the input streams to generate the output streams, and broadcast the output streams to audio devices within the vehicle. The WAU may employ various strategies for synchronizing different types of audio streams, based on relevant factors. As a result, audio playback at the vehicle may be performed with tighter integration with vehicle speakers and tactile transducers, and a flexibility in routing the audio streams may be increased.
