If you aren't going to use DAHDI, don't install the asterisk16-dahdi
package :-) Without that package, codec_dahdi wouldn't even be on your
system, and you would never have had this problem. With that package
(which provides codec_dahdi, among other things), the assumption is that
you want that module loaded.

You don't need to have any of these DAHDI packages installed at all.
