  1. I have an mkv file that does not output sound on my tv because of the audio format. Looking for a solution. thanks
    So far i demuxed it and tried audacity and a couple of other programs to convert it but what comes out is just noise

    When i open the file in any audio editors it says it cannot determine the format and it's asking me to choose attributes and rate (hz). I only know this:

    Audio #1
    ID                          : 2
    Format                      : TrueHD
    Codec ID                    : A_TRUEHD
    Duration                    : 1 h 59 min
    Bit rate mode               : Variable
    Bit rate                    : 3 659 kb/s
    Maximum bit rate            : 5 634 kb/s
    Channel(s)                  : 8 channels
    Channel positions           : Front: L C R, Side: L R, Back: L R, LFE
    Sampling rate               : 48.0 kHz
    Frame rate                  : 1 200.000 FPS (40 spf)
    Compression mode            : Lossless
    Stream size                 : 3.06 GiB (20%)

    Or from TrueHD to FLAC with AudioMuxer. Saves space.

    PS: You have to update manually the files at "C:\Users\UserName\AppData\Roaming\AudioMuxer" , because they're not up to date. The files that gets installed are way too old.... Eac3to, libFLAC.dll, mkvmerge.exe & mkvextract from mkvtoolnix, MediaInfo CLI.exe...and maybe the 7z files in the "Encoding" Folder. All x32 bit.

    You can do it in one process using PopcornMKV Audio Converter no need to demux or muck about with command line routines. Just load the file in and select what you want. The default settings are TrueHD to DTS
