No audio during playback after converting DTSHD to LPCM

    hi,

    I had a rip of a blu-ray movie that I wanted to make compatible with the ps3 for streaming, it played fine in powerdvd 9 before I converted the audio, and now I have only video and no audio during playback in powerdvd 9. Here is what I did:

    I demuxed the .m2ts file using the HD stream extractor in MeGui, giving me a .h264 video file and a .dtshd audio file. I then used eac3to to convert the dts master audio track to lpcm.

    Here is the log file from eac3to:

    eac3to v3.17
    command line: eac3to F:\BDmovies\Qos\qos.dtshd F:\BDmovies\Qos\stdin.pcm
    ---------------------------------------------------------------
    DTS Master Audio, 5.1 channels, 24 bits, 48khz
    (core: DTS, 5.1 channels, 24 bits, 1509kbps, 48khz)
    Decoding with ArcSoft DTS Decoder...
    Swapping endian...
    Remapping channels...
    Creating file "F:\BDmovies\Qos\stdin.pcm"...
    The original audio track has a constant bit depth of 24 bits.
    eac3to processing took 9 minutes, 27 seconds.
    Done.

    I then ran the stdin.pcm file through Pcm2Tsmu to make the file compatible with tsmuxer using the following command:
    F:\eac3to\Pcm2Tsmu13\Pcm2Tsmu F:\BDmovies\Qos\stdin.pcm F:\BDmovies\Qos\stdout.pcm

    Finally, I muxed the original .h264 video file and the stdout.pcm audio file to a .m2ts file using tsmuxer and that worked without any errors. Now my new .m2ts file does not have any audio during playback in powerdvd 9. I tried WMP and that doesn't work either. Did I miss a step somewhere or did I do something wrong during the conversion to lpcm?

    here is the log file from the eac3to stream extraction within MeGui:

    eac3to v3.16

    Video track 2 contains 152832 frames.
    eac3to processing took 16 minutes, 31 seconds.
    Done.

    I will try converting the dtshd track to dolby digital and see if that works...

    I just realized that I have no idea if I actually have the ArcSoft DTS Decoder needed to decode the DTS-HD track. If I don't actually have this installed will eac3to still try to decode the track? the log file shows that it is using it to decode but I have never installed that, unelss its built into powerdvd 9 or something.

    update, I converted the dts-hd track to dolby digital and it plays perfect in powerdvd 9, I still have no idea why the lpcm track doesn't work. Also, I noticed the counter in powerdvd shows that the movie is 9 hours long, when its only 1 hour and 46 minutes in length. It shows the proper length when viewing the original BD rip, why would the remuxed file be any different?

    Judging by your first post it looks like you have Arcsoft installed and working properly with eac3to. The problem is with PowerDVD, I'm not sure what it is though. Maybe check if PDVD is set up to decode LPCM.

    On another note I'd stop using that PDVD garbage and use Arcsoft... since you have it installed.

    As long as it muxed fine, the PS3 will also play the LPCM fine. Just make sure your settings in the PS3 is are correct and connected properly to a compatible audio receiver.
