.mkv only sending 2ch even though file 5.1

Postby Shawzborne » Sun Sep 08, 2013 11:52 am

Hi Guys,

I am using an Denon AVR-E400 with HDMI only. I have a 5.1 speaker setup. And PS3 is wired via gigabit cat 6 Ethernet for between pc and router as well as between PS3 and router/switch

Im still new with how PS3 Media server works but my current audio trans-code settings are:

-Use LPCM for audio
-Keep AC-3 Tracks
-Keep DTS Tracks
-640
-eng


here is the detailed look at the file that I am trying to play:

Audio
ID : 2
Format : DTS
Format/Info : Digital Theater Systems
Mode: 16
Format settings, Endianness : Big
Codec ID: A_DTS
Duration: 2h 3mn
Bit rate mode : Constant
Bit rate: 1 509 Kbps
Channel count: 6 channels
Channel positions : Front: L C R, Side: L R, LFE
Sampling rate: 48.0 KHz
Bit depth : 24 bits
Compression mode : Lossy
Stream size : 1.30 GiB (15%)
Language : English
Default : Yes
Forced : No


And here is what the ps3 is receiving via the info bar:

Linear PCM 2 ch.
48 Khz
1.5 Mbps

MPEG-2
7 Mbps

Am I doing something wrong?

Thanks guys

Shawn

That is what the PS3 will display for the audio for 5.1 DTS tracks (part of the trick to support 5.1 DTS). Your receiver should be properly playing 5.1 DTS. Is it not?

so it's actually playing true 5.1 surround and not 2ch right even though the ps3 says it is

Correct. The PS3 supports DTS audio for disc media only, so PMS tricks the PS3 by wrapping the audio in a 2ch LPCM header that the PS3 just passes through. Your receiver should still properly recognize and play it as a 5.1 DTS track.

A quick verify... Does this line in a recent commit then require a "n:2" to keep the trick working?

Code: Select all
Supported = f:wav   a:dts         n:6   s:48000   m:audio/wav


(in other words: is 5.1 DTS audio still working on a PS3 in the latest snapshot?)

If somebody else doesn't beat me to it, I can try to test this tonight. Not sure if I still have a DTS sample file, but I should be able to find one somewhere.

Actually, I would attempt it, but I don't have a 5.1 surround system. I look forward to your results. ^_^
