DTS streaming audio issues with PS3

[Dmancol]

Hello,

I cannot hear sound through my amplifier when I am streaming .mts files to my PS3 from a networked attached drive.

I know the file works fine because I can decode it through my windows 7 media PC and I hear the audio.

here is my configuration:

Networked Attached Drive - recognized, by the PS3, no issues playing .mts files encoded with AC3.

PS3 - original version 4.31 connected to my amplifier through HDMI , audio output format settings set to Linear PCM. ( i have tried bitstream and it does not work)

Amplifier - Onkyo TXSR604 - plays DTS and in fact the DTS logo comes on when the movie plays but there is still no sound.

Any ideas on what i can do to fix this?

If you are using HDMI cables, disable "Keep DTS audio in stream", and enable "DTS/FLAC->LPCM remux"

This will make PMS pass the DTS to the PS3 as multi-channel LPCM ( Linear Pulse Code Modulation ) uncompressed audio. These two options are in PMS to allow movies with DTS to be streamed to the PS3 with minimal quality loss (less than encoding to AC3)as it only accepts DTS on hard media (DVD discs or AVCHD discs).

"Keep DTS in stream" option is for optical cable set ups. This basically hands off the decoding of DTS audio to your amp.
Optical cables, though they sound nice, are limited in they can only pass 2 channel LPCM uncompressed audio, which limits it for the new HD audio formats (True-HD, DTS-HD Master Audio), and I believe only up to 5.1 audio max with regular Dolby and DTS......no 7.1 audio. Also, optical are just delicate if you're not careful.

HDMI is the way to go in my opinion. Especially with the new low cost home theatre setups that come with multiple HDMI inputs to allow source switching. I just picked up a HT-SS370 Sony BluRay amp system. I only use my Xbox360 with optical.

Just thought I would note that the PS3 will do DTS from AVCHD and you can put AVCHD on a USB Thumb Drive. Yes it must be formatted FAT32 and thus have the 4GB limit but tsMuxeR can be set to split the M2TS file(s) to 4GB chunks. So basically you can have a movie that is way over 4GB since it just breaks it up into smaller files (and the movie will play as one seemless experience with no "hiccups" when one file ends and the next begins).

The nice thing about this is that you will have DTS audio support. In fact you get multiple audio and subtitle stream support doing it this way.

The downside is that you will have to use tsMuxeR to convert your M2TS or MKV to AVCHD and that shouldn't take much time but then you'll have to copy it to the USB Thumb Drive and if your drive is slow then that can take forever.

Please note that if you do this that you should run the tsMuxeR output through the program AVCHDMe20 as it makes sure all filenames are 8.3 compatible (will change things without breaking anything to make it so if need be). You'll need that for PS3 USB playback.

Just copy the AVCHD structure to the ROOT of the Thumb drive and off you go!

P.S.
I forgot to mention one big "fly in the ointment"
AVCHD cannot be cropped. That means you need full 1080p / 1920x1080 video or full 720p / 1280x720

Thanks for the help but I am trying to avoid any transcoding that PMS does. Also when I use PMS there is definite loss in video quality and my video sometimes skips/jumps.

I will keep hunting for an alternative.

I hope you find a good alternative. Is the video/audio that you're using something you downloaded?

The AVCHD process that I explained does not do any re-encoding nor any transcoding. It is just demuxing from one format and remuxing into another. It takes a little bit of time (not much) and the quality will not be lost. However the video cannot be cropped and that often times is the only thing preventing this method.

I had to deal with all this myself as my computer is too far from my HDTV to connect with directly and all I have is a PS3 but I just bought a blu-ray drive as a Christmas present to myself (a burner for my computer) and OMG it makes life so much easier.
