Release Notice:

Dolby Atmos MAT audio playback:

Some content devices output Dolby Atmos audio in "Dolby Atmos MAT" format, a new audio format that adds Dolby Atmos metadata into lossless pulse-code modulation (PCM) audio. The content devices are designed to prioritize internal buffering for high quality video when playing Dolby Atmos MAT contents. Therefore, the buffering process might cause random audio cut-outs. This is reported by various users with content devices that outputting Dolby Atmos MAT format:

From time to time, the data transmission may not be 100 percent perfect due to multiple reasons such as network speed inconsistency and variable data bit-rate of the content. For streaming and broadcast content, video signal is always prioritized over audio, thereby causing potential intermittent audio drop outs for a very short period of time. This is especially prominent when it comes to any high resolution content, which requires more intensive processing power and bandwidth.

After the Dolby Atmos SSE upgrade, the soundbar is doing a much heavier load of processing vs before. The system is processing Video frames up to 4K with active HDR in real time (Dolby Vision and HDR10 standards with HDCP 2.2) and passing it thru to the TV. Concurrently, it is also processing and upmixing Audio from PCM, Bitstream, all Dolby or DTS codecs to 7.2.4 channels of audio. Layering on our exclusive Spatial Surround Processing (SSE) audio upmixing portion is especially computing power intensive as most content are only recorded in 5.1 or 7.1. When multiple devices are connected together in a chain, with each device feeding different audio and video codecs to the soundbar individually, the soundbar needs a few seconds to process and decode the signal properly. Every time when the user switches programming, stop, pause, fast forward or rewind, this entire process initiates again, thereby requiring time to initialize.
