Audio on DVDs has been compressed in to formats like Dolby Digital and DTS which are "lossy". "Lossy" means that when the data is uncompressed it's not identical to the original but the goal was to get close. The Audio on CD's is uncompressed.
"Lossless" compression is a form of compression that reduces the size of the data, but when uncompressed, the data is restored to it's original state.
The LPCM format used on some Blu-Ray discs is uncompressed, but this takes up a lot of space that could be used for other purposes.
The Dolby Digital and DTS formats available on Blu-Ray discs are compressed and lossy, and you can use them like you would on a DVD player and play those tracks back via toslink, HDMI, or analog connectors.
The Dolby TrueHD and DTS-HD/MA formats are compressed but lossless.
Because the powers that be don't want people to be able to get their hands on the original audio in digital format it can only be played back via HDMI to a receiver that supports HDCP copy protection, or output as analog.
Bottom line... if you want the best possible audio you need one of the following:
1) A player that can decode lossless formats and output them as LPCM to an HDMI compatible receiver.
2) A player that can output lossless formats as-is and bitstream them to an HDMI 1.3 compatible receiver.
3) A player that can decode lossless formats and output them to 5.1/7/1 analog outputs that you can wire via RCA cables to any 5.1/7.1 receiver that supports multi-channel inputs.
