Answer 1

Your error log is very succinctly self-expressive:

Deactivating an audio session that has running I/O. All I/O should be stopped or paused prior to deactivating the audio session

It tells you the problem and also the solution.

Right now you're doing something like this:

[[AVAudioSession sharedInstance] setActive:NO
               withOptions:AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation
                                             error:nil];

You should however, first stop the audio player instance and then set the activation status to Yes or No.

[yourAudioPlayer stop];
[[AVAudioSession sharedInstance] setActive:NO
                   withOptions:AVAudioSessionSetActiveOptionNotifyOthersOnDeactivation
                                                 error:nil];

Refer to Apple Documentation to see values of enum AudioSessionSetActiveOption.

Also see: Apple Documentation on setActive:withOptions method

As for your second error

PropertyManager was compiled with optimization - stepping may behave oddly; variables may not be available.

see this excellent answer.
