Popping Sound

Sounds like a bug. Assuming you're on the Public Beta, it comes with a built-in Feedback Assistant app for filing bugs like these, which can be opened from the second page of the Home screen on your iDevice. You can also send your feedback directly to Apple with Feedback Assistant.

Sounds like its just a bug, could you file it, attach a simple example, and report the bug number here?

I don't think it's resolved at all. My app is all about playing music files from the user's music library. It works fine with everything but audio books in iOS 8.4. With audio books, nothing works right: asking a track to play often starts a different track, and the currently playing item is incorrectly reported and is not updated.

I've been having this same issue in beta 3 and now beta 4. Garbling sound once and a while but not all the time. Also Audio goes away every once and a while. In order to get it back either a rebbot or what I have been currently doing is opening up the midi setup app and changing the output to any other format this kicks it back on. I've tried all formats it does it with them all 44100 - 192000I am using a Apogee Duet 2 (USB straight into an 5k iMac)

I'm not sure whether it is definitively solved yet, but I did disable Default Folder (which isn't fully compatible with El Capitan yet anyway) and so far sound has been fine. It may just be a coincidence. And I don't see why it should be linked. But so far my audio hasn't failed...

I can confirm this issue, tested with Display Audio on my Cinema Display. It's also the case for my FireWire audio interface (Focusrite Saffire PRO 14). My Digital Out is working fine.

I see. That sounds legit. Thanks a lot for your quick help. Cheers!

I am having the exact same issue !! I've been going on about this all day and I can't seem to find a solution. All this started in the morning when I saw that ios 9 public beta 2 was available, so natuarally I immediately started to dowload the version. After it was done downloading i began to install it, once it was installed my phone was stuck on a slide to upgrade screen and when I slide the screen an apple logo appeares with a progression bar under it; it'd get to about 20 percent then go back to the slide to upgrade screen. Frustarted, I pushed the lock and home button at the same time and still got the same thing. Eventually I just reset and restored the phone. Now it was running on ios 8.4 and i restored it from an old ios 8.4 back up. Then i proceeded to upgrading back to ios 9 and ios 9 public beta 2 was successfully installed BUT i wanted to restore it from an ios 9 public beta 1 backup. I restored the phone and my backup was there and ready to go except when I selected the back up from icloud, it b

I get the same result that LCS did: an error message about a missing return, that's all.There are a couple of situations where Xcode seems reluctant to let go of an error message from an earlier compilation attempt. Maybe that's happened to you. You can try any of the following:1. Put the text cursor immediately to the right of the y in sampleArray and press Esc. This should pop up a completions list, and sampleArray should be the only thing in the list. Press Enter to use the completion.2. Select and cut the entire line of text from that method. Wait a few seconds to make sure you get a different error message (missing return), then paste the line back in.3. Clean the build folder: Option + Clean Build Folder from the product menu. (This should get rid of old build transcripts.)

Sounds like a weird caching issue. Are you behind any sort of proxy?

USB Audio drops sporadically in latest Beta. Unplugging and re-plugging reastores for a while.

I could, except that this error appears on 100's of video sources across multiple releases of iOS. It is a specific error message that AVPlayer is adding to the log as a result of a decoding event in the HLS stream. So this isn't a bug, is a designed response to a specific condition in the segmented media stream. The question is one that Apple should be able to describe what would trigger the log entry. Is this a mismatch between the audio and video frames PTS values in the current or active media segments? Is this a media segment to media segment PTS problem and the renderer in AVPlayer can't align the video and/or audio frames? Or is this from another structural problem in the segmented stream.Without being able to describe what is right or wrong in the media stream in response to what Apple intends with this error message, I can't tell them what their bug is - it may be that all these media streams have some fundamental segmentation error.I may have to file a bug to get their attention, I

DId you include Core Audio public utility folder?https://developer.apple.com/library/ios/samplecode/CoreAudioUtilityClasses/Introduction/Intro.html
