What kind of routes could I get back from kAudioSessionProperty_AudioRoute property?

Question

Apple guy tried to be funny and wrote in the docs:

("Headphone," "Speaker," etc.)

What kind of return values are possible in reality?

Answer 1

I ran 'strings' on the CoreMedia framework (iOS4.2 SDK), and the following strings seem reasonable and are grouped together:

• ReceiverAndMicrophone
• HeadsetInOut
• HeadphonesAndMicrophone
• SpeakerAndMicrophone
• HeadsetBT
• LineInOut
• Default

Command was:

strings -a -o CoreMedia | less

# CoreMedia is from /Developer/Platforms/iPhoneOS.platform/Developer \
# /SDKs/iPhoneOS4.2.sdk/System/Library/Frameworks/CoreMedia.framework

Answer 2

He wasn't being funny, those are actual values. The only one I've seen that he didn't outline is "LineOut"
