Turn off the sound(Ring/Silent) but still have sound

[shuefeng]

Hi all:

I try to use SCListener (SCListener: The Easy Way to Detect iPhone Microphone Sound Levels) to listen the input from mic.
If the sound level approach the threshold, there is a sound effect will be played. (I use AVAudioPlayer to play the sound effect).

However, I found some strange behavior.
I try to turn off the sound(Ring/Silent), but the sound effect still be played.
If any one can give me some suggestion, what can I do.

Thanks,
Fen

I'm not sure about that specific sample you are looking at but issues like this are usually related to what audio session category you are using; so you might want to start there.

Thank you for your suggestion.
I study the audio session category, the category I used is kAudioSessionCategory_PlayAndRecord.
This category won't be silent when Silent/Ringing set as silent.

Thanks,
