When selecting a device that simply doesn't exist with --audio-device, AudioUnit will still initialize and start playback without complaining. But it will never call the audio render callback, which leads to audio playback simply not progressing. I couldn't find a way to get AudioUnit to report an error at all, so here's a crappy hack that takes care of this in most cases. We assume that all devices have a kAudioDevicePropertyDeviceIsAlive property. Invalid devices will error when querying the property (with 'obj!' as status code). This is not the correct fix, because we try to double-guess AudioUnit's behavior by accessing a lower label API. Suggestions welcome. |
