There was previously a workaround for this issue on affected players: switch the player to "PCM" decoding mode, and you could avoid the drop-outs without sacrificing sound quality. I use an OPPO BDP-103 for Dolby Atmos playback with no problems whatsoever. Happily the issue does not affect OPPO's later players (BDP-103, BDP-105). Some of the Dolby Atmos titles currently on the market do use seamless branching, and so they have audio dropouts when played back on a player that doesn't support seamless branching properly. Seamless branching is a method used by DVD and Blu-ray players to branch from one scene to another scene that may be on another part of the disc (not in physical order). Some of the earlier OPPO Blu-ray players like the OPPO BDP-83, BDP-93 and BDP-95 (for example) have problems with Blu-ray Discs that use a feature called "seamless branching" combined with a Dolby TrueHD soundtrack. I say, "should" because there are some exceptions. Inexpensive Blu-ray players that support bitstream output of Dolby TrueHD soundtracks, like this LG model, should work perfectly with the new Dolby Atmos and DTS:X Blu-ray titles. Similarly, if you want to check out DTS:X (the other immersive surround format), then any player that supports DTS-HD Master Audio with bitstream output should work for that. When you send that Dolby TrueHD soundtrack out over HDMI to a Dolby Atmos-capable receiver or processor in bitstream mode, the receiver or processor detects that it is actually a Dolby Atmos track and processes the sound accordingly. Dolby is wrapping up the Atmos "objects" (the height information) into a Dolby TrueHD wrapper that works with existing players and receivers. What kind of spec will I need to look for in my blu ray player's documentation to determine this?įor the most part, any Blu-ray player that supports Dolby TrueHD and bitstreamed output should support Dolby Atmos. I plan to buy an Onkyo receiver and speakers that can play Dolby Atmos tracks but I can't find anything that says whether my LG blu-ray player that's several years old can make use of the Atmos soundtracks or if I have to upgrade my player as well.
