Error setting audio session active to 0! ‘!act’

[dmarques42]

I integrated OpenEars into my app successfully, and have been using it for almost a week, no problem, playing with parameters, all fine.

It was working fine early today. Then, suddenly, this afternoon, I am getting an error when I load it (direct build from Xcode) onto a device:
Error setting audio session active to 0! ‘!act’

And, never any response to sound.

That error occurs always immediately before “Pocketsphinx is now listening.”
It works fine when I test in the XCode simulator, and I have tried backing out all changes I made in the past week. Somewhere I did something it did not like.

I believe it was still working when I added a test for microphone approval
([[AVAudioSession sharedInstance] requestRecordPermission:^(BOOL granted)),
but I backed that out as well as all reference to [AVAudioSession sharedInstance].

I also tried
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
err = [audioSession setActive:YES error:nil];
NSLog(@”sttOn: %d”,err);

after the above, but it returns 1, so all seems to be fine.

Any suggestions?

Welcome, please check out the post Please read before you post – how to troubleshoot and provide logging info here so you can see how to turn on and share the logging that provides troubleshooting information for this kind of issue.

I test on both an iPad 5th generation (iOS 11.4) with 128 GB (115GB free) as well as with an iPhone (iOS 10.3) with the trace below. The app behaves as if the microphone were turned off. I have checked the microphone on both (“Hey, Siri” works) and that it is enabled for the app (as seen in the trace).

Let me know if there is anything I can provide. My code is essentially the same as the sample code but a callable init routine. The app is integrated into the Coronalabs framework, so init and on/off are called from Lua and results are passed back. Happy to provide the code it it would help.

Interesting that the log seems to say I have ‘donkey’ twice, but a search of my code only finds one instance, there is a single list of words as in the example.

Does the sample app get the same error on the same device?

[dmarques42]

Oh, very sorry, dumb of me not to go back. The original ‘merge’ of the sample app with my Coronalabs framework DOES work, it hears the words. Certainly points to a bug of mine. I’ll see if I can just go back and build up from there, but it will take me a few hours, have to do it tomorrow. Sorry about that, I should have tried. Though, I still don’t understand what is different, both are pretty bare bones.

[Halle Winkler]

No problem, glad you have a known-working reference point you can check things from. I don’t support Corona, so getting it working well in that context has to be done without my assistance unfortunately, but I would recommend just taking your time and assuming it’s something minor which will turn up when retracing your steps if you use the sample app as the guideline.

[dmarques42]

Working again, but it looks like a race condition or other timing problem. I essentially replaced line-by-line, and the only difference is when I called the init. If I delay calling it until after the app has mostly started, it gives the error, but if I call the init routine during the framework startup (as, I must say, your documentation recommends), then it works.

Anyway, thanks for your time, and sorry for the distraction.

[Halle Winkler]

Glad it’s working for you!
