Default ps3 True HD and umcompressed PCM?

I heard that the playstation 3 does not support lossless sound! If this is true then it is deffinatly not worth it for me to get one! does anyone have one and use lossless sound?

I don't know where you heard that, but it's 100% false. PS3 supports PCM and TrueHD lossless audio.

The PS3 doesn't support bitstream output of lossless sound and unless they change the HDMI chip in one of the never ending variations, it never will.

What it does do is support HD audio decoding internally and output it as PCM which is just fine and works quite well. Master Audio is not in there yet but will be. TrueHD works right now.

Yeah, the ps3 is one of the most powerful HiDef players available on the market. It has been since it was released, and the frequent firmware updates ensure that it will continue to be at the head of the pack in this application.

The only "downside" to the ps3 is that it will never display DTS-HD MA icon on your receiver, since it decodes the information internally and all that your receiver does is send the actual sound channels unmolested to the connected speakers. Since the audio format is already "real sound" and not a digital file stream when it reaches the receiver, it simply displays "Multi-Channel PCM" or something similar, since that's exactly what it's receiving.

So long as your ps3 is connected to your receiver via HDMI, the proper firmware is loaded on the ps3 (and the supporting output options are checked off in the audio setup menu of the playstation), and your receiver is connected to the speakers properly then you will get pure, uncompressed hi-def audio through your setup.

PCM is a digital sound format as well. It is not an encoded digital format, like Dolby Digital and the like. "Real sound" would be an analog signal, one that is passed over an analog cable, which requires resistance, since any analog signal is nothing but a current/voltage signal. HDMI doesn't carry any analog signals, only digital ones.

Right, that came out a little unclear, thanks for the clarification. My intention was to relay that it is a discrete channel of ready-to-relay sound, which needs no complex decoding by the audio receiver, all that needs to be done is to have the digital audio streams converted to analog and relayed to the speakers..which pretty much all audio receivers can do.
