Hi, I think I got it: With the attached patch I am successfully able to use channel maps in vala in my program. Here are the details:
1. Remove the "has_destroy_function=false" attribute. It was only necessary because of a bug in vala which is fixed in 0.12. [1] 2. Add sizes to all fixed-size arrays to make vala recognize them as such. Using symbolic constants for this is not yet supported. [2] 3. CardInfo struct: Move the brackets in the list of available profiles to the type to make it clear that this is a dynamically-sized array. [3] Please merge this into master if you have no objections. Best regards Alexander Kurtz [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=622773 [2] https://bugzilla.gnome.org/show_bug.cgi?id=647788 [3] http://0pointer.de/lennart/projects/pulseaudio/doxygen/structpa__card__info.html
