DTS-HD audio support

[Josip]

Hi,

I have a Samsung PS58C7000 and a Pioneer VSX-521 both have ARC (audio return channel) enabled. I am playing an MKV with DTS-HD audio and the amp is only picking up DTS not DTS-HD.

Is there a new profile that needs to be used or some setting enabled in Mezzmo?

Any help would be greatly appreciated.

Cheers,


Josip

Hi Josip,

Can you please post FFmpeg information on one such file?

If you are using the "Samsung C" device profile for the Samsung, then we should be passing that file through natively, it's then up to the end device to decode the audio. Does it display DTS-HD for any DLNA files? Perhaps the TV is sending audio as DTS downstream and thus the receiver picks it up as such. What are the settings for audio output on the TV?

[Josip]

Hi Dennis,
Thanks for your help.

1: I am using the Samsung C profile
2: I have tried Samsung D and Samsung BDP profiles and still play DTS-HD
3: When watching the movie and going to the Sound Settings menu all there is to choose from is PCM and DTS

Cheers

Sounds like the TV only supports DTS and that's why it displays like that - Mezzmo does not convert the file, so audio should be preserved as-is.

[Josip]

I am using HDMI in the ARC (audio return channel) port. Shouldn't the tv be passing the audio directly to the amp which is capable of decoding HD audio?

[Paul]

I assume it is passing it directly, but it may be describing it as DTS, because the TV doesn't understand the difference between DTS and DTS HD, for example. Or, the TV is converting audio to DTS on its own before passing to the amp. You'd need to check the manual or contact Samsung support to get more technical data, as I'm afraid I don't know for sure what's happening at that level. Basically, audio is passed untouched from Mezzmo to the TV, but then it's up to the TV to pass it to the amp.

[Josip]

I will contact Samsung support to get some more info from them.

I have another movie that has a TrueHD audio track. It won't play any audio. It comes up with the error message: "Audio Codec Not Supported" I am aware that my tv might not be able to handle HD audio. But is there a way that I can at leats play the standard AC3 core file?

That file should be transcoded (or actually remuxed, keeping original video) if you're using the "Samsung C" device profile. Can you please check that the device profile is correctly set and that transcoding is turned on?

If all looks good, please enable logging (see this thread: http://forum.conceiva.com/showthread.php/419-FAQ-How-to-turn-on-diagnostic-logging), delete the transcoded file then try playing it again and once you get the error from the TV, stop the server and send in the logs to support.

I just extracted the AC3 core from the TrueHD file and inserted it into the mkv.

I also have a BD-C5900 and it cannot play TrueHD or DTS-HDMA from either DLNA or from usb HDD. I tried extensions .mkv, .ts & m2ts and still doesn’t work. I am very disappointed as I have an AVR that is capable of decoding HD Audio and neither my Samsung TV nor Blu-ray player can read them. :(

Thanks anyway for your help Dennis. :)
