No audio track recognized

When I open a m2ts file, Avidemux 2.6.11 doesn't recognize the audio tracks. The QuickTime player won't either. But VLC and MPlayerX does so I know its there. Any ideas? Here's the VideoSpec report on the audio:

provide a small sample of video (100 MB max) with such a DTS (Coherent Acoustics issue). (Basic DTS support is possible there)
