Maybe something you can ask google support?Ĭouple of quick things - you mention using AVAudioSession for input and output - I'm going to guess you mean you have an AVAudioSession configured for PlayAndRecordCategory but since AVAudioSession itself doesn't provide any audio data specific APIs you may also be using the RemoteIO? So, not knowing how clients are expected to work with the youtube-ios-player-helper, it's hard to comment on what their expected behavior is or why they need to change the hardware sample rate. The number of developer requests for specific features are really important and are always taken into account when trying to prioritize features for future versions of the OS. It would help if you filed another request even though it is a duplicate. We have an open feature request to add KVO support for the sample rate property of AVAudioSession. If it can be changed by other components, there should be a way to get notified in order to be able to take it into account! The sample rate of the audio session is a key information for an audio app. A change of sample rate does not trigger any call to the handle route notification or the media services reset notification.Īny idea how to get notified when the sample rate of the audio session is changed? The sampleRate property of AVAudioSession is not key value observable. I did some research, tried a few a few things, none worked. Is there any way to get notified when the sampleRate of the audio session is changed? The problem is that the youtube player, on which I have very little control, modifies my AudioSession, and especially changes the current sample rate, resulting in some serious buffer issues in my audio code. My app uses AVAudioSession for audio input and output with real-time interaction, and also uses the Google pod youtube-ios-player-helper to display YouTube videos.

I got some crashes in an app for quite some time, and I finally understood why.
