OpenAL doesn't work when using AVAudioRecorder and AVAudioPlayer

[pawegiwo]

hi.
i have been troubled about audio problem for several days. i don't think OpenAL get along with AVAudio functions.

i have my own OpenAL class. ( wrapped the MyOpenAL class )
my app start to record using AVAudioRecorder. i stop recording. and then i clicked the "OpenAL Play"button that play any sound using OpenAL.
i can't hear it.
but i can hear my recording when i clicked the "AVAudioPlayer Play" button using AVAudioPlayer.

i tested oalTouch,avTouch,SpeakHear sample code.
they resulted same.
in oalTouch, when AVAudioPlayer stop, OpenAL stop playing simultaneously. this is why i think so.


Does OpenAL have the problem using AVAudio~ Functions together?

I was googling for a long time. but i couln't find out the solutions and the same problems issue.

thanks for reading mine.

Does anyone know the solution??
