I haven't looked at all of your code; I will tomorrow.
You can get rid of the info variable from module_init
and module_audio_init_spd.  It isn't used for anything.
In module_init from ibmtts.c, here are the only two places where info is used:
Declared at line 406,
and set to g_string_new("") at line 414.
You should be able to just delete both of those.
In module_audio_init_spd, here are the places where info is used:
declared at line 1119,
set to g_string_new("") at line 1124,
used as the first argument to g_string_append_printf at line 1197.
Again, you should be able to just delete all three of occurrences.

Line 1197 of module_utils.c is interesting.  That is an error message,
and my first thought is that it needs to be propagated to the caller,
via the status_info argument.
However, abort is called, so it really doesn't matter.
