What? Are you for real? Optical does not allow TrueHD? **bleep**! I will check that info tonight! Wicked, i really thought optical was better. Thanks
No problem, just Google “optical HD audio” and you’ll find a bunch of info.
Just to add to my previous comment, the limiting factor associated with Optical cables is the S/PDIF specification that pretty much all consumer audio equipment adheres to. The physical cable could, in theory, send HD audio as it has a bandwidth up to 125Mbps. The S/PDIF spec limits bandwidth to only 1.5Mbps, crippling performance.
It seems that i have to switch my PS3 to an HDMI port on TV and use the Live Hub HDMI to connect to my Audio Decoder since it only have 2 HDMI Ports and one is for cable TV already ( I wish it had 3… ).
I dont remember the home theater model but the player/decoder is a bd-c6900 yes. The files are in mkv and none of them that have DDTrueHD seems to send audio. Only Dolby Digital or DTS MA…

You need to explain what you are plugging the HDMI out from the WDTV into.
However if you you are trying to use the network playback features of the BD-C6900 then that is a totally different question. Samsung devices are well-known for not supporting many (actually most) media codecs/formats with network playback.
*Did you unplug your optical cable? Is the Hub set to output via HDMI only? The only circumstances I can think of that would stop DDTrueHD working is if your amp still thinks it should be playing audio via optical or the files themselves are incorrectly encoded. As requested earlier in the thread, post the MediaInfo output for one of your non-working files and well take a look. Google MediaInfo, it’s a free app, very useful.

Nothing jumps out as being wrong in either of those MediaInfo outputs.
In your first file, I thought perhaps that it had Header Compression enabled (which shouldn’t be an issue) but to try remuxing it anyway.
Yet the 2nd file doesn’t appear to have that and still doesn’t work.
I really don’t know what to suggest; all I can say is that the DDTrueHD files I have output as DDTrueHD and play fine on my Hub.
Not sure where you’re getting your files from (apologies if you encoded them yourself) but the most likely culprit is incorrect encoding. Try remuxing with MKVmerge, just to rule that out.
Something else to try is downloading the same files I’m testing with.
Go here and grab some DDTrueHD files from the Dolby section:
sorry.
