[source setPosition:alpoint(float, float, float)] cannot work when reverb is "Yes"

[ryokanoshoh]

Hello everybody.

I am going to create new Wadaiko (Japanese drum) app on iPhone 5.
I have problem that when "[OpenALManager sharedInstance].currentContext.listener.reverbOn" is YES,
"[source setPosition:alpoint(float, float, float)]" cannot work.

I confirmed that when "[OpenALManager sharedInstance].currentContext.listener.reverbOn" is NO,
"[source setPosition:alpoint(float, float, float)]" can work.
I think "Reverb" object have some problems, but I cannot
find the point of these on all souces.

If you have method to solve these problem, please let me know.
