AVAudioEngine error #8

Describe the bug

AVAudioEngine error after calling client.startContext()

AVAEInternal.h:109 [AVAudioEngineGraph.mm:1397:Initialize: (err = AUGraphParser::InitializeActiveNodesInInputChain(ThisGraph, *GetInputNode())): error -10868

AVAudioEngine.mm:167 Engine@0x2835ec560: could not initialize, error = -10868

Errors are shown after

Client init
After audioEngine.prepare() is called in AudioRecorder.swift. Errors are reported to the delegate by line 441 of Client.swift.

Only happens on device... everything works as expected in simulator.

Steps to reproduce

Occurs after Client init and again after calling client.startContext().

Environment

Platform: Mobile
OS: iOS 15.6
Package version: 0.3.0

Was able to resolve by running AVAudioSession.sharedInstance().setCategory(.playAndRecord) before creating Speechly client. Unsure why this only caused issues on device & not in simulator.
