问题
I am running the Hello World example from AudioKit-macOS-4.7.2 using macOS Mojave 10.14.5 on a Mac mini (2018).
When running the example using the inbuilt speaker, sound is heard, all is well.
When running the example with a UE BOOM 2 bluetooth speaker connected, no sound is heard and I get the following output:
2019-07-12 10:09:19.615436+0100 HelloWorld[1874:44088] [AudioHAL_Client] HALC_ProxyIOContext.cpp:958:IOWorkLoop: HALC_ProxyIOContext::IOWorkLoop: the server failed to start, Error: 0xE00002D6
I can play iTunes through all speakers fine.
What is the problem and how do I fix it?
Edit: If AudioKit uses AVAudioPlayerNode then I suspect this is due to the problem described here.
