Confirmed; I can correctly decode the 16-bit files in 00-05. A few 
questions and notes:

* Is it necessary (or supported) to decode the 20- and 24-bit files?
* If so, what are the command line options?
* als_08/als_08_6ch96k24b.mp4 makes FFmpeg crash; I know it's not 
supported yet but it should at least not crash:

0x00115788 in revert_channel_correlation (ctx=0xb00c60, bd=0xbfffe30c, 
cd=0xb00fb0, reverted=0xb00e50, offset=0, c=6) at 
/Users/melanson/ffmpeg/ffmpeg-main/libavcodec/alsdec.c:1178
1178	    while (dep < channels && !ch[dep].stop_flag) {

I'll get the 6 supported 16-bit files into FATE.

Thanks...
