VirtualDub2 does not recognize .AC3 .AAC audio files

Hello,
I'm using VirtualDub2 v44282

Although I installed the AC3ACM64 plugin as well as many codecs (see attached file),
When "Caching input driver (default mode) selected, VirtualDub2 does not recognize .ac3, .aac… audio (see attached file).

On the other hand, if the input driver is "Audio/Video interleave input driver (internal" (see image), VirtualDub allows me to select "AC-3 ACM Codec" in 3/2 channels, no Mono or Stereo available (see image).
So, when I start saving the video, VirtualDub returns the error message "Error initializing audio stream compression. Not installed audio codecs could compress the source audio to the desired format…" (see attached image). Yet, AC3 codecs, AAC are installed (see attached file installed codecs above).

In fact, every time I have to extract the audio file, convert it to .mp3 and add it as "Audio from other file".

I'll appreciate yr help

Finally, I find how to
Use Audio -> Conversion to downmix to Stereo or Mono. "Lame MP3" and "AC-3 ACM Codec" become available in Stereo and Mono.
Audio -> Full Processing Mode must be enabled.
