Presented herein are system(s) and method(s) for fast audio and angle switching via multiple demux buffers. In one embodiment, there is presented a circuit for decoding data. The circuit comprises a processor, a system clock, a plurality of queues, and at least one decoder. The processor demultiplexes a plurality of elementary streams from a multiplexed stream, wherein each of the plurality of elementary streams include portions, wherein each of the portions include time stamps. The system clock maintains a clock reference. The plurality of FIFOs correspond to the plurality of elementary streams and FIFO each of the plurality of elementary streams, wherein each of the plurality of FIFOs include a front end, and wherein the front end of each of the plurality of FIFOs stores the portion of the corresponding FIFO that includes a time stamp that is proximate to the clock reference. The at least one decoder decodes selected ones of the plurality of elementary streams by decoding portions at the front end of the FIFO corresponding to the selected ones of the plurality of elementary streams and a newly selected one of the plurality of elementary streams by switching from decoding portions at the front end of a FIFO corresponding to one of the selected ones of the plurality of elementary streams to decoding portions at the front end of a FIFO corresponding to the newly selected one of the plurality of elementary streams.
