Extract Dolby TrueHD Audio from MKV

[Spasch]

I have an MKV file that has a single audio stream, Dolby TrueHD. This does not play any audio when I play the file through my WD TV Live, so I am looking for some software to extract the audio stream so that I can convert it to AC3 and add it back in.

I have tried mkvtoolnix and eac3to, but neither are able to extract the stream.

TIA

Have you tried popcorn mkv audio converter?

I've not tried that.. I'll fire it up now and have a look, thanks..

EDIT: Bah, it all looked so good until I hit the run button..

Unsupported Audio codec: A_TRUEHD.

Something that I noticed is that Makemkv will do that automatically if you select the DD button only and not the Truhd button.

Or at least it seems to. When I put the resulting MKV file in MediaInfo after I do that it just shows a 640kbs AC3 file as the audio.

Thanks, but I already have the MKV with TrueHD audio. I am looking for a method of extracting the TrueHD stream so that I can convert it to AC3 and reinsert it into the MKV..
