Hi Zoul/whoever....
I encountered a problem using Finch - I was opening and releasing again alot of sound files and a particular point in the project sounds would stop loading - the error code form ALOpenFileFromURL... was 43 - File not found ... my solution in the end was to make sure that files were closed by adding AudioFileClose (and keeping a record of the fileId) to the dealloc in Sound.m... my solution is probably not graceful and maybe naive but seems to work for now - so i thought i would post in case it helps anybody else
thanks, Ross
