Reinstating sound file for gnumch
This does not work. How do I call gc_file_find_absolute from Python?

Line 385.

As far as I understand from py-mod-utils.c, I should call:
- gcompris.utils.gc_file_find_absolute

But I get:

AttributeError: 'module' object has no attribute 'gc_file_find_absolute'

I also tried calling:
- gcompris.utils.file_find_absolute
- gcompris.gc_file_find_absolute
- gcompris.file_find_absolute
