* Fix two typos of wrong filenames (these two are not case mismatches) in audio_id.c (one used a ',' instead of '.' and used wav as extension, the other missed a '-')
* Don't use case insensitive matching of filenames in audio_GetIDFromStr anymore as our filesystems aren't guaranteed to be case insensitive (this should cause no problems together with the above fixes)
* Use calloc instead of malloc and a for-loop to allocate an array of NULL pointers in sound_Init
