I've added new sound files i got from our sound designer, they're either .caf or .aif files. Both result in the following error when played using SoundEngineManager playSound:

Error loading looping file info: 4
(gdb) continue
2009-06-24 21:19:21.291 ArmageddonAgain[706:207] Can't load sfx_m_fade_in01.aif
2009-06-24 21:19:21.318 ArmageddonAgain[706:207] *** Assertion failure in -[SoundEngineManager addSound:], /depot/ArmageddonAgain/AudioSupport/SoundEngineManager.m:222
2009-06-24 21:19:21.332 ArmageddonAgain[706:207] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Failed to load sound'

At first i thought it's because the soundfiles were in stereo but after matching them with Sapus' sounds (16 bit, 44 kHz, Mono) it still crashes on the iPhone. Then i read about little & big endian mismatch but i have no idea how to check or fix that.

At the moment we're just using the files as plain old .wav files (long live the plain and simple formats).

I have two questions:

- is this "error loading looping file info" something common and does it have a common cause and solution?
- are there any drawbacks to using .wav files instead of .caf/.aif for sound playback?

I don't know about your error but there are no drawbacks to using .wav files. Caf files are basically a wrapper around some other format so you could have a caf file that wraps little endian PCM (like a .wav) or a caf file that wraps IMA4 compressed audio or the myriad of other formats that are supported.

I use .wav for uncompressed PCM, .caf for IMA4 compressed (because I use afconvert to create the files from .wav) and mp3 for compressed audio that I want streamed i.e. background music.

My problems with the sound effects with GeoRain in 3.0 firmnware are due the caf files .. I just converted them to wav and everything works withouth touching the source code (well just for ointing to the wavs).

Wier that some caf work and other don't

The error message I got is:

Error -1500 loading sound at path: /var/mobile/Applications/ADDC498A-1AB6-4DA5-97F0-F1EB51B25986/GeoRain.app/2mejor.caf
