Conclusion:
One should not use Waveformat Extensible as codec-ID for AC3 as most used
players expect 0x2000 (which is standard as far as I could find out)
One should investigate the muxing bug. (Thanks for opening the issue)
Sorry for not posting output before, I just reproduced the bug earlier with
selurs given example.
Hope there is no needed output missing. I added the files I used to reproduce
and analyse the issue.
