People are basing this specualtion on a fact sheet that does not list bitstreaming of HBR audio as a capability. That by no means proves that it for a fact cannot do it. Lets not talk of speculation as fact please.
Here are the specifics:
The HDMI ver. 1.3 transmitter chip in the PS3 is manufactured by Silicon Image and is their part number: SiL9132. This is not part of their commercial HDMI chip offerings and they do not currently publish on their web site a spec. sheet for this chip. This chip was sold by Silcon Image specifically to Sony for the PS3 and this was their first product to have a HDMI Ver. 1.3 interface. A short time later Silcon Image introduced their mainstream SiL9134 chip which is now being widely used in consumer electonics devices including standalone BD and HD-DVD players. The details for the SIL9134 is available from their web site HERE
As described in this article
, the SiL9134 was announced by Silicon Image as their first commercial HDMI ver. 1.3 transmitter chip offered (as the SiL9132 was producted specifically for Sony). This announcement was published on Oct 1, 2006 which was about 7 weeks before the PS3 went on sale, so the SiL9134 may be, or not be, really different from the SiL9132 used in the PS3 (the SiL9132 may just be the Sony OEM version of the SiL9134 -or- the SiL9134 might include some enhancments).
There has been speculation, but no specific information released by either Silicon Image nor Sony of the bitstreaming capabilities, or limitations, of the SiL9132. What limited official info that has been released on the SiL9132 did not specifically mention support for bitstream output of the advanced lossless audio formats while the full spec. sheet for the SiL9134 does mention this capability. Several people posting on various forums (including AVS) have incorrectly posted speculation as if it were fact, that the SiL9132 does not support this feature that is supported by the SiL9134. Many such postings have cited as proof other earlier postings or blogs that in fact provided no proof for such claims. I have not found any posting that links back to any authorative source either at Silicon Image or at Sony and these are the only two sources that truly know what their products can or cannot do. If anyone has such proof let's see it.
