just following up, I found it:

     readformat = ao2_bump(ast_channel_readformat(chan));
-    if (ast_set_read_format(chan, ast_format_slin)) {
+    if (ast_set_read_format(chan, ast_format_slin48)) {
         ast_log(LOG_WARNING, "Unable to set channel '%s' to linear
mode\n", ast_channel_name(chan));
         ao2_ref(readformat, -1);
         return -1;

Maybe it's worthwhile to make it configurable. I'll file an enhancement.
