When the other sdk set avaudio play and recorde, the unity ios fmod by bluetooth can't hear the voice

when I set
int ToIos()
{
NSString* category=@“AVAudioSessionCategoryPlayAndRecord”;
int option=12;
AVAudioSession* session=[AVAudioSession sharedInstance];
if(option!=-1)
{
[session setCategory:category withOptions:option error:nil];
}
else
{
//[session setCategory:category error:nil];
}
}

I cant hear the voice or hear error voice by bluetooth in ios. Anyone can help me.

Hi chuyuwei,

It looks like your problem is related to apple apis. You should ask your question on the Apple developer forums.
