I have a VERY STRANGE PROBLEM playing audio files on Nokia 6600. Wav files will not play from phone memory, but play from MMC.

I first noticed the problem with my application, where a wav file is loaded and played programatically. The app worked if installed on memory card.

After some testing it turned out that the wav file I use cannot be played even using the Nokia 6600 recorder application, but only if the file is saved to phone memory. The very same file can be played if it's located on the memory card. Using FExplorer, it turned out that the file cannot be played from any location in phone memory!

I have seen a similar question posted in some other thread, no answer though! Does anyone have an answer? I can only assume that this is a phone bug. If so, how can such a huge flaw pass Nokia QA?
