Missing audio from recovered AVI files

[campe1]

I have several AVI files that I recovered from accidental deletion from a memory card using EASEUS Date Recovery Wizard and/or CardRecovery, plus the help of Digital Video Repair with one of the files. The images have been recovered for all 4 movies, but none has any sound. I'm trying to figure out if the sound is recoverable, so let's look at one file as an example. File properties in Windows Explorer tell me:

Size: 3.65 GB
Video Length: 00:01:39
Video Total bitrate: 221184 kbps
Audio Bit rate: 0 kbps

In GSpot, I see the Container includes 3.62 GB unneeded bytes at end of file, Video: 34.4 MB (0.92%), AVI Overhead: 3.62 GB (99.08%).

I have some small hope that perhaps my audio is stored in the container, but there is a flag or some simple setting that needs fixed (or a handy utility that will extract my audio from the container).

Does anyone have any ideas or suggestions for me?

Thank you so much!

1) Try to open the files in VirtualDub and check if it see the audio.

2) Try to recover the files again with Recuva.
