mkv TrueHD sound taking forever to start

HD-DVD "Dawn of the Dead" ripped using MakeMKV with TrueHD 5.1 selected
Windows7 x64 VLC player 1.1.11
ffdshow indicates True HD decoder is libavcodec

When I play Dawn of the Dead mkv in VLCMP, video starts instantly but it takes over a minute for the sound to be heard. While video is playing, Media Information -> Statistics show Audio [Decoded 0 blocks Played 0 buffers Lost 0 buffers]. After about 1-2 minutes, the sound finally starts and the statistics show activity. If I click the time line to skip to a different part of the movie, it will take another 1-2 minutes for the sound to come on.

Any idea what's causing the sound decode delay?

Thanks very much.

Use VLC 2.0 and try it.

I installed VLC 2.0 but this did not fix the problem. Audio doesn't begin until 2:03 mark.

I will figure out how to clip a sample from this file and will upload it as soon as I do.

I don't know if this tells you anything, but this is what appears in Messages when the audio begins playing at the 2:03 mark:
To help you, we need messages, to completely understand what your problems is.
To fix this, please be sure before you start the playback to:
  1. Open: Tools -> Messages.
  2. Set Verbosity to 2
  3. Start playback to reproduce your issue
  4. Save text in a file or copy into clipboard
  5. Then paste the full resulting log here between [​code]and[​/code] (or use Pastebin.com if it's too long)
Also don't forget to name your Operating System and provide the VLC media player version.
Thanks very much.
