Thank you aDope, the trick with mapping the shortcut using the NumPad works great, and you can even use the normal Cmd-Shift-7 shortcut without the NumPad after.

Submitted FB7761200:
Initializing audio I/O using Xcode 12.0 beta (12A6159) on the iOS Simulator results the app crashing with the following console logs:
HALBIOBufferManagerClient::GetIOBuffer: the stream index is out of range
HALBIOBufferManagerClient::GetIOBuffer: the stream index is out of range
[aqme] 255: AQDefaultDevice (1): output stream 0: null buffer
[aqme] 1778: EXCEPTION thrown (-50): error != 0
Initialize: Mach message timeout. Apparently deadlocked. Aborting now.
This can be easily reproduced e.g. with the "AUV3Filter iOS" app that is part of this sample project:
https://developer.apple.com/documentation/audiotoolbox/audio_unit_v3_plug-ins/creating_custom_audio_effects
Steps to reproduce:
Launch app
Expected results:
App launches
Actual results:
App crashes in AURemoteIO::Initialize()

We’re seeing the exact same issue, minus the logs from augraph and aurioc:
HALB_IOBufferManager_Client::GetIOBuffer: the stream index is out of range
HALB_IOBufferManager_Client::GetIOBuffer: the stream index is out of range
HALB_IOBufferManager_Client::GetIOBuffer: the stream index is out of range

Start: Mach message timeout. Apparently deadlocked. Aborting now.

I had the same issue today with some of our videos.Interestingly, after changing the poster frame and hitting "Save" again it worked for me without error.

Sounds like there’ll be a new Xcode 11 GM to fix this. From the developer portal (emphasis added):Please note that apps built with Xcode 11 using named colors may experience lookup failures (with no value returned) when the app runs on iOS 11 or earlier. This will be fixed in a future Xcode update. To avoid this issue, raise the minimum deployment target to iOS 12 or later to submit to the App Store now, or rebuild with the next Xcode GM candidate seed when it’s available.https://developer.apple.com/ios/submit/
