As announced last week (see Blu-ray.com, September 16), new firmware version 3.50 is now available for the PlayStation 3, which enables support for the Blu-ray 3D specification on all incarnations of the PS3 console. However, Sony Computer Entertainment has confirmed that DTS-HD and Dolby TrueHD won't be supported on the PS3 during 3D Blu-ray playback.
Thus, when playing back a 3D BD with a DTS-HD Master Audio soundtrack, the PS3 will output DTS. When playing back a 3D BD with a Dolby TrueHD soundtrack, the PS3 will output Dolby Digital. This affects both PCM output and bitstreaming (available on slim consoles only).
