Failed to open audio recording device [name]. SDL Error: CoreAudio error (AudioQueueStart): -66681 [MacOS]

[mail2mhossain]

When using our app, if an audio input or output device is unplugged, I can switch to another available device on all platforms (Windows, MacOS, Linux). However, after plugging the device back in, the app can only switch back to it on Windows.

On MacOS, I encounter the following error: "Failed to open audio recording device [name]. SDL Error: CoreAudio error (AudioQueueStart): -66681".

This indicates that the unplugged device is still in use or blocked by SDL2 or MacOS. I have tried the following code in the "InitRecordingDevice" method after calling "CloseAudio()", but it still does not work:

SDL_QuitSubSystem(SDL_INIT_AUDIO);
SDL_InitSubSystem(SDL_INIT_AUDIO);

I have also added "SDL_ClearQueuedAudio(dev)" in the "CloseAudio" method before calling "CloseAudioRecordingDevice", but this has not resolved the issue either.

Are there any solutions for this problem?

Seems a SDL2 issue.
Create an issue on SDL2 project then add here its reference for other users
