AVAudioPlayer Output to Speaker Problem

Question

After searching around for how to send AVAudioPlayer output to the iPhone's speaker, I found this:

http://stackoverflow.com/questions/1064846/iphone-audio-playback-force-through-internal-speaker

Despite setting the category correctly to AVAudioSessionCategoryPlayAndRecord, this solution doesn't seem to be working for me and won't even let the build compile, giving me this error:

"_AudioSessionSetProperty", referenced from:

... ...

ld: symbol(s) not found collect2: ld returned 1 exit status

Am I not including something? I'm importing AudioToolbox, AVFoundation, and CoreAudio.

My class implements AVAudioSessionDelegate, AVAudioRecorderDelegate, AVAudioPlayerDelegate, and UITextFieldDelegate.

Any help would be greatly appreciated!

Add the AudioToolbox and AVFoundation frameworks to your project by Right-Cliking on Frameworks -> Add -> Existing Frameworks
