4.6+ Sound Interruption - Siri, Alarm, Call - doesn't resume on focus

We have a major issue - Unity 4.6.4/4.6.5, both mono or IL2CPP - where once the app is interrupted by external source such as Siri, an Alarm or a phone call, upon returning to the app, there is no sound.

AudioListener.pause is false.
AudioListener.volume is 1.
AudioSettings.dspTime is stuck and is not increasing anymore following the interruption. We found no way to "unstuck" it.

Following Apple guideline, this could be a submission blocker.

We encountered the same issue but we use FMOD as external libraries. We first of all thought that FMOD was involved.
We try a lot a smart and stupid things, we only "solve" the problem by adding a sleeping time on application resume.

- (void)applicationDidBecomeActiveUIApplication*)application
{
printf_console("-> applicationDidBecomeActive()\n");

// Add a delay to avoid SIRI issue.... Ugly workaround
[NSThread sleepForTimeInterval:0.1f];

...
}

Did you find something useful?

 

Hello,

We have the same problem using Unity 5.2.1f1 and xCode 7.0.1

If we open Siri inside the app and then close Siri, the sound do not resume. We've checked that the mix and volume are ok.

If we open and close the notification tray after the above situation the sounds works again. It seems to be an Unity-iOS / iOS9 bug.

Do anyone knows if there is a Unity-Side solution without getting into native?

Thanks

 

This is still an issue using 5.3.4p4. We have encountered this in our app after interrupting it with Siri. Sometimes (like around 10% of trials) there is a small visible UI lag after coming back to Unity and the audio dsp stops updating until the next app lose/gain focus event. Did you receive a bug report already? (Unfortunately, I cannot send in the project I'm working on.) The "[NSThread sleepForTimeInterval:0.1f];" workaround seems to be working so far.

 

I have the same issue, but I have android phone. I tried to use OnApplicationPause method and debug what happend but nothing helped.

 

Many bugs have been submitted, but closed under "cannot reproduce". Which is odd, since I personally submitted a stripped down project that we were able to repro the bug 100% of the time on all iOS device.

 

First post in the thread; http://fogbugz.unity3d.com/default.asp?701940_rps5ppprv03f47b2

There should be a stripped down project associated with it.
