I ran some tests, including one that led You. Even tried the following 
conversion types:
char * samples = (char *) frame-> data;
and anyway, the result is a -1 for all x, from 0 to frame->datalen-1

My task was to remake the module mod_avmd, ie file mod_avmd.c. And this 
problem has put me into a dead end, to the point where I moved my job to 
another server. In other operating environments do not have this problem. I 
wrote about this in more detail in the Issues:
