It was working fine until I tried to update Open Ears from 0.9 to 1.01. With that version I have problems with, I guess, the AudioSessionManager: when open ears is starting, all sounds from my main application are muted. I tried the soundMixing option, but it didn’t change anything (the recognition loop is always active through the app)
Do you know what could be the reason of such a difference between these two versions ? Do you have an idea on how to solve it ?
Thank you for your help,

Open Ears is working perfectly well in both situations, it’s just on the AIR app side that sounds are muted with the 1.01 version.

I don’t really think that is your issue but it would be a good first step to set the level. Also it has nice new features, one of which is easier logging which might show us if there are any errors in the audio session manager.

Still the same issue. Here is the log : http://dl.dropbox.com/u/14292529/log.txt

And if it may help, I’m not using Flite, so I don’t need Opean Ears to access to speakers

I have an AIR app that launches a native process, in this case, Open Ears.
After some investigation, I commented every AudioSessionSetProperty in AudioSessionManager, and it’s working fine again (on iOS 5.1)… except on iPad 1 (iOS 4.3.5) : after Open Ears’ launch, sounds continue playing, but Open Ears doesn’t seem to “hear” anything, as when I’m talking, nothing happens.

You have a fix ,which is to break AudioSessionManager, but this will also probably have negative effects on OpenEars’ performance. However, the previous AIR overriding that was working with the versions before 1.0 most likely also had the same effects so it might not seem like a problem. My random guess about the iPad is that of all your 4.x compatible devices, it may be the only one with only a single mic and whatever the AIR audio session settings are, they may force recognition to occur on a second mic.
