As of 6/30/07, the only audio from a BR disc that comes out of the BDP-S300 via the S300's HDMI output is Dolby Digital 5.1, DTS 5.1, or multichannel PCM (either decoded DD/DTS or a raw PCM track.) The 6 analog channels each carry an analog line level signal of each of the 5.1 DD and DTS signals included on BR discs. IMPORTANT: These are analog signals, not LPCM.
In the future, if Sony wants to remain in business and not lose all its credibility, Sony will provide updated firmware to its customers who purchased a BDP-S300. That improved firmware will make it possible for BR discs that have Dolby True HD or DTS HD encoded audio to output analog signals at line level from the HDMI and the 6 analog channels. This is how HD DVD players handle such material today.
Dolby True HD and DTS HD will never be available via the SPDIF o HDMI connections because Sony's chose to use older and less powerful decoder IC's that can not and will never stream these formats to a receiver or PrePro with Dolby True HD and DTS HD decoding capability. If you decide to keep this player, find a preamp or receiver with 6 analog/line level inputs. Purchasing equipment with decoding capability will be of no benefit to individual who seek to listen to material encoded with advanced codecs such as Dolby True HD and DTS HD.
NOTE: Corrected to reflect Gonk's comment. Is this correct now?
Nice write-up, but I think you are making a mountain out of a temporary molehill.
1. The S300 does what it does very well, and very similar to most other BD players, and even HDDVD players
2. The output of the SPDIF will never stream the high bitrate codecs because it lacks the bandwidth. That is true of all SPDIF today. What they can do, and what both format players do is downmix the high bitrate codecs to something that the SPDIF can handle. Which is encoded DD or DTS.
3. The HDMI output is LPCM from decoded codecs because that is the way both format players chose to do things.
4. There are no announced plans from any BD or HDDVD mfg to allow the passing of TrueHD or DTS-HD unencoded to any receiver. And the disks are authored in a way that won't allow it anyway. The prime reason given is to ensure syncing of video and audio.
5. The analog outputs are just that analog. They do not and probably never will, pass the DIGITAL, undecoded codes out. That's not why they are there.
So while I think Sony was very misleading in the owner's manual for the S300 and wanted people to look and think it did decode TrueHD and DTS-HD, I do think that Sony will provide a firmware upgrade that will do that decoding.
Assuming that is so, then Sony's S300 will be doing exactly what SOME, but not all of the other BD players are doing. NONE of the BD players on the market today, nor the future ones that have been speculated about, will pass undecoded high bitrate codecs.
So if you think that the lack of undecoded pass through is important, then you need to rethink your choice to go to either BD or HDDVD because it appears that it will never happen and the light on your super-duper AVR for TrueHD or DTS-HD will probably never light up, at least not from a signal coming from your HDDVD or BD player.
