kAudioHardwareServiceDeviceProperty_VirtualMainVolume ANR

Using

let address = AudioObjectPropertyAddress(
   mSelector:kAudioHardwareServiceDeviceProperty_VirtualMainVolume,
   mScope: kAudioObjectPropertyScopeOutput,
   mElement: kAudioObjectPropertyElementMaster
  )

Using Xcode13.1, App freezes.

Tips: Using Xcode12, mSelector using kAudioHardwareServiceDeviceProperty_VirtualMasterVolume is worked.

  • ANR stack:

    main thread is 259 Call Backtrace of 25/32 threads: Backtrace of Thread 259: libsystem_kernel_dylib     0x1ae629954 mach_msg_trap + 8 libsystem_kernel_dylib     0x1ae629d00 mach_msg + 76 0x0000000000000000 *** ... MyApp        0x102892d20 $18setDefaultD12OutputVolumeySbSfF + 380

    So this issue related Xcode13?  And what's the different between kAudioHardwareServiceDeviceProperty_VirtualMainVolume and kAudioHardwareServiceDeviceProperty_VirtualMasterVolume?
