PCM_S16LE stereo audio to AAC in MP4 not working anymore

Hello,

unfortunately V2.6.7 (Windows) doesn't seem to support converting PCM_S16LE stereo audio to AAC (Faac) when saving to MP4 (not V2) anymore. I've also tried r8999 without success. It worked with V2.6.6.

I typically use FFMPEG to create the input files for Avidemux the following way (this reduces audio sync trouble):
ffmpeg -i InFile -acodec pcm_s16le -vcodec ffv1 OutFile.avi

When I play such a file in Avidemux V2.6.7 r8999, I can't hear any sound. However, the menu item Audio->Select Track shows the correct track. When I save to MP4 with  AAC (Faac), the resulting file has no audio track at all according to VLC.

By the way: I love Avidemux. And the stability on Windows is really much better now, so your efforts were successful!

I just tried, seems to work fine with plain PCM / Stereo / 16 bits
Do you mean reverted PCM like the ones found on DVD ? (can never remember if they are LE or BE)
A sample file would help

Thanks for the fast reply. I've uploaded an example here (21MB, just click on "download file"):

It's a short TV record converted with FFMPEG (see original post). VLC plays the sound, Avidemux doesn't.

The problem is reading the file, it cannot read the audio track properly

In case it helps; this is the FFMPEG version I used (Windows):
