Audio missing when opening an Avisynth script in WMP & VirtualDubMOD

[aln688]

I have an MKV file which contains an MPEG-4 h.264 video stream and an AAC audio stream. I've installed Avisynth 2.5.8 and MatroskaSplitter, otherwise known as the Haali Media Splitter, as well as FFDshow.

My goal here is to convert the MKV file to an AVI. Yes, I've read all the tutorials on how to do this, including numerous YouTube videos, but for some reason I don't hear any audio. At present, when I double click the .MKV file, it opens in Windows Media Player and sound is present. When I open my .AVS script in WMP, as below:

DirectShowSource("D:\test.mkv")

...I get video, but no audio. If I open the .AVS script in VirtualDubMOD (latest version), same thing, the video will play but no audio. If I open it in VirtualDub (latest version), worse results, I get a black window and the video will not play at all!

I'm using Windows 7 64-bit. I just tried the CCCP pack (un-installed FFDshow before hand), no difference.

Any ideas? If you need screenshots of anything, please let me know.

Thanks.

You might have to set ffdshow as the preferred audio decoder using Preferred Filter Tweaker in windows7.


OR use another converter that does not need avisynth, like xmedia recode, winff (ffmpeg frontend) or an older version of handbrake (0.9.3).

I'll give the tweaker tool a try, thanks.

Thank you! Without knowing why, the 32-bit FFDshow was using the Microsoft AAC filter, despite me specifically setting it to FFDshow when I installed this package. Many thanks.

Question, I notice VirtualDub now loads fine and plays the video. Is conversion in VirtualDub preferrable over VirtualDubMOD? I know VDM is an older piece of software.
