Audio Device Behaviour

Audio devices preferences can be found by clicking on preferences under the user menu:

Inside Preferences, under the Audio tab you will find device settings:

Please make sure the device you want to use is connected. If it is connected and it is configured as your default device for input/output on your OS you shouldn't need to adjust any settings, just leave as default. But if you still want Zulu to always use that specific device for input/output you should definitely select it. Zulu will save the device id and try to use it, if it is not connected it will fall back to the Default device. Please note that Zulu will only list devices that are connected, even if you have previously selected a different device (It will still be saved and used if you connect it back).
