Hi,

I'm using this library to read an audio stream (of a click track) and determine when a click happens to start a playback of a light show. Unfortunately the program crashed every now and then, but not in a reproducible interval. The error thrown is the following - any idea what's going on there? :(

This is the code which reads the stream (Initialize and Terminate are called once on programm start and exit), with the line throwing the error marked: https://github.com/StageAutoControl/controller/blob/master/pkg/cntl/waiter/audio.go#L37

Looking forward to any helpful input - and thanks in advance!

At first glance I see that there is no synchronization around Audio.fanOut. You might want to run with the race detector enabled to see if there any other such issues.

Also, are you sure Audio.Wait should call Audio.start? It seems like the stream ought to be started only once, and Wait should only sign up listeners.

So, assuming that the audio.go code is working as expected, any other suggestions regarding the portaudio error? 🤔 😐

only one process / routine / method ever calls the audio.Wait method.

Regardless, in the output you posted I see many goroutines in Audio.notifyWait (which is only reachable from Audio.Wait). There is concurrency going on there without synchronization. Either you need to use a mutex around Audio.fanOut or you need to make sure those Audio.readStream goroutines exit before you return from Audio.Wait.
