Popping Sound

Installation slow, but no issues.General impression: Massively improved performance on a late 2013 MBA. Fans were spinning often on Yosemite before, now system is cool (literally). Also, it behaves a lot faster. So that's good and it really makes me not want to go back.Some observations in random order:Eliminated custom content from /usr, which broke LaTeX. Needed disabling rootless to restore.Java problems were avoided by switching to Java8 before.VirtualBox works w/o problems.Skim is broken. Which is a big one for all students probably :-(Magic Trackpad behaves weirdly (operational, except mouse cursor not moving) when connecting MBA to TB display. Using insomnia to not have it sleep when connecting solves it.TB connected audio device (through belkin hub) stopped working, after a reboot it was there againFefe's blog shows white boxes when pinch-zooming in SafariThe announced new tiling features are at odds with my being too stupid to make them work in any way.TotalSpaces 2 could be made work with a

Haven't tried with a queue but even a single sound item causes crashes. Try running in simulator to see if it asks for a bluetooth headset as this is the behaviour I and a few others are getting.

Since your issue doesn't sound identical, you might want to start your own thread, rather than tagging onto someone else's, so you can better track and mark solved should that occur.Good luck.

I have upgraded my iPad Air to ios 9 beta 1 also. Actually those devices even my iphone 6 plus doesnt have this problem all the time. Until my iphone keep to be used around 1 day without reboot (may be low in memory at that moment), then I tried to record something and found that black background with sound only from that video. I'd never found this problem on or before ios 8. I guess that is memory problem?!

Giebler, if the user interacts with the watch app there is no budgeting, it is only background processes and local or remote notifications that are budgeted at what sounds like twice per hour. So if I user changed projects in the watch app you can get the shared instance of CLKComplicationServer and extend or invalidate the timeline without any issues.

The problem is that when you do this self.delegate = MainViewController()you're creating a brand new instance of MainViewController that is not the one that's actually on the screen. You need to pass a reference to the instance that's actually in your view controller hierarchy. Typically this is done in prepareForSegue, something likelet destVC = segue.destinationViewController as FooViewController destVC.delegate = selfwhere FooViewController is the class that defines the delegate property. It sounds like your situation is a bit more complex as you have some other VCs in the middle there, but the key point is the same - you need to pass the actual reference to the specific instance of MainViewController on down the chain. You can't just create a new one.

I've begged them for this in bug reports 3 or 4 iOS versions ago, I've written Tim Cook, (and Steve Jobs) for this.I discussed ways I am using past and current Apple tech, UI and frameworks to work around trying to keep my apps at least usable, and instead of Apple helping, those work arounds disappear in the next update of iOS/OSX, this has happened 3 times... the last time, I didn't even think it was even close to something Apple didn't want apps to do, nor would any normal human, yet the next version of iOS/OSX, I could not, nor can anyone, any longer use this extremely useful method... that is just not right.... there just is no reason why it should have disappeared, not battery, not security, not any reason. (and why it was such a big surprise when an Apple employee said: you/your app should not be able to do such and such) I am going to leave that as vage as it sounds, for fear of losing something else.I've grown to use bug reports sparingly, and not at all, twice bitten three times shy, and I'

If you want unfettered access to background execution, you should consider other mobile platforms. The multitasking framework and APIs exposed by Apple represent their opinionated belief that one can provide a high quality, total-device experience to the user (i.e. easy to preserve battery life in the face of battery-hungry developers), with full-featured background APIs for developers.It's been five years since the first introduction of multitasking on iOS 4: iOS's approach has evolved over that time, and it seems clear that they will not be adding any capability for unterminated background execution in the near future. They've added many, many APIs to multitasking and background execution to support the vast majority of use cases, but it's clear that unbounded background execution without GPS or audio work is one they consider off-limits.

Based on the answer from @tom_witkin here it sounds like the answer is no.

Thanks for your response PBK! Happy to know that it will be simple.Apologies if I'm being dense, but this will also work in the case that they buy a new device and install the application again? Sounds like it will since it's based on the receipt, not the original install. Just want to check though, because it seemed like there was a lot of chatter online about this case.Thanks for your help!

Replying to myself,If I init the node just as above and instead of running the action SKAction.play() I run the action SKAction.playSoundFileNamed(, waitForCompletion: false) i.e. leaving the name of the sound file empty it works. At least plays the sound. Have yet to test if it actually does the 3D effects.

While there is no there is no “realtime tap” currently in AVAudioEngine, one way you may want to go about tacking this is by writing your own effect v3 AudioUnit (Audio Unit Extensions) and then inserting that into the engine.The idea would be to create and publish the AudioUnit as an effect, then create an instance of it in AVAudioEngine using a new iOS 9 AVAudioUnit method:+ (void)instantiateWithComponentDescription:(AudioComponentDescription)audioComponentDescription options:(AudioComponentInstantiationOptions)options completionHandler:(void (^)(__kindof AVAudioUnit * __nullable audioUnit, NSError * __nullable error))completionHandler NS_AVAILABLE(10_11, 9_0);Of course this is more work than just having an AVAudioEngine provided realtime processing tap, so please file an enhancement request for that feature https://bugreport.apple.com/Audio Unit Extensions were discussed at WWDC 2015 and are going to provide a very powerful way to to extend audio processing on iOS 9 (AU component
