Added on February 25, 2008, 11:28 pmBitstream is raw digital stream. It can contain miscellaneous data types: linear PCM, DD, DTS, DTS-HD etc. The only reason you wouldn't want to use bitstream is if you're not using the player's digital audio outputs. PCM will not send Dolby Digital or DTS to the receiver even if the DVD player is compatible with those audio formats.
You can only get a "true" 5.1 uncompressed PCM via an HDMI cable. (you would need a receiver with HDMI decoding capability at the other end also of course).
If you specify uncompressed 5.1 PCM for audio playback and you are using an optical cable, you only get 2 Channel, (stereo), since it cannot carry all the bandwidth of a full 5.1 track. HDCP prevents an optical cable from delivering multichannel high definition audio...2.0 uncompressed is the best you can get. Assuming you are connected via optical cable, 2.0 uncompressed is the best you can get, which then is utilized by the Dolby 5.1 matrix, (or whatever other sound field you select), in your receiver. That is why, with an optical cable, can get normal 5.1 Dolby digital, the core mix which is much better than the standard, but it is not "true" high definition audio.

--------------------------------------------------------------------------------
The title says it all..
What exactly is the difference between Bitstream vs. Linear PCM? ... the two options you have to choose from when choosing HDMI Audio Out from the settings. What exactly do I need to choose in order for the sound to come out the way it should? Does Linear PCM need to be chosen in order for PCM soundtracks from a blu-ray disc to output at its optimum?
When I play Pursuit of Happyness in 5.1 PCM (Bitstream enabled), my receiver will show that PCM is active. When I play it in 5.1 English (Bitstream enabled), my receiver will whos that Dolby Digital is active. But the 5.1 English sounds louder than the 5.1 PCM. But shouldn't that be the other way around... 5.1 PCM is uncompressed. When I play both soundtracks with Linear PCM enabled, my receiver will only show PCM active (even if I play the 5.1 English soundtrack).
Any help is appreciated.
Thanks

The receiver can only play .wav sound (PCM) so at some point it needs to unzip (or decode) the DD track into a PCM stream in order to play it. Setting the PS3 to bitstream makes the PS3 send whatever's on the disc to the receiver, where setting to Linear PCM causes it to be converted to PCM in the player before sending to the receiver. Hence, when playing the PCM soundtrack, the receiver gets PCM regardless of the setting.
You might want to leave the setting as Bitstream so at least you know when you're accidently using the DD soundtrack because your receiver will tell you. In terms of volume, this is seperate from compression. Compression will cause the sound quality/clarity to decrease but it can still be recorded at a much higher volume to give you poor quality but very loud sound in comparison to the PCM soundtrack.
