I've been searching all over to find an answer to this question. I know that FairPlay/HLS supports audio Streams since there's obviously audio in video, but I'm wondering if this is practical? Also is there any way to stream FairPlay DRM encrypted content without HLS? or if I use HLS could I create only a single audio bitrate format in order to save on hosting costs? I work on and Audio Book app that requires DRM for some content. Also any links to documentation, videos, tutorials, blog posts... etc on the topic would be awesome too. Very much appreciate anyone who takes the time to answer this. I wish this was more explicitly talked about on the Apple Dev site, but it seems very geared towards video streaming.

Wondering if anyone can help me figure out what could cause this crash? It seems to happen only on one of my coworkers iPhone 13 running iOS 16.2 my phone is a iPhone 11 Max Running iOS 16.1 and this crash is not happening. #0 (null) in UIKitNavigationBridge.containingNavControllerFromLastAttemptedPop.getter () #1 (null) in UIKitNavigationBridge.containingNavControllerFromLastAttemptedPop.getter () #2 (null) in UIKitNavigationBridge.isInTransientPop.getter () #3 (null) in UIHostingController.resolveRequiredBridges(in:allowedActions:) () #4 (null) in UIHostingController.didMove(toParent:) () #5 (null) in @objc UIHostingController.didMove(toParent:) () #6 (null) in -[UIViewController removeChildViewController:notifyDidMove:] () #7 (null) in -[UINavigationController removeChildViewController:notifyDidMove:] () #8 (null) in -[UIViewController dealloc] () #9 (null) in -[UINavigationController viewDidDisappear:] () #10 (null) in -[UIViewController _setViewAppearState:isAnimating:] () #11 (null) in __52-[UIViewController _setViewAppearState:isAnimating:]_block_invoke_2 () #12 (null) in __52-[UIViewController _setViewAppearState:isAnimating:]_block_invoke () #13 (null) in __NSARRAY_IS_CALLING_OUT_TO_A_BLOCK__ () #14 (null) in -[__NSSingleObjectArrayI enumerateObjectsWithOptions:usingBlock:] () #15 (null) in -[UIViewController _setViewAppearState:isAnimating:] () #16 (null) in -[UIViewController __viewDidDisappear:] () #17 (null) in -[UIViewController _endAppearanceTransition:] () #18 (null) in __97-[UITabBarController transitionFromViewController:toViewController:transition:shouldSetSelected:]_block_invoke_3 () #19 (null) in -[UIViewController _executeAfterAppearanceBlock] () #20 (null) in -[_UIAfterCACommitBlock run] () #21 (null) in -[_UIAfterCACommitQueue flush] () #22 (null) in _runAfterCACommitDeferredBlocks () #23 (null) in _cleanUpAfterCAFlushAndRunDeferredBlocks () #24 (null) in _UIApplicationFlushCATransaction () #25 (null) in _UIUpdateSequenceRun () #26 (null) in schedulerStepScheduledMainSection () #27 (null) in runloopSourceCallback () #28 (null) in __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ () #29 (null) in __CFRunLoopDoSource0 () #30 (null) in __CFRunLoopDoSources0 () #31 (null) in __CFRunLoopRun () #32 (null) in CFRunLoopRunSpecific () #33 (null) in GSEventRunModal () #34 (null) in -[UIApplication _run] () #35 (null) in UIApplicationMain () #36 (null) in closure #1 in KitRendererCommdowon(_:) () #37 (null) in runApp<A>(_:) () #38 (null) in static App.main() () #39 0x0000000100466550 in static AppRoot.$main() at AppRoot.swift:13 #40 (null) in main () #41 (null) in start ()
