How can I detect audio device changes?

2 views (last 30 days)
I would like to detect changes to the list of connected audio devices WITHOUT restarting matlab.
This does NOT work (= does NOT show devices connected/disconnected after matlab was started):
deviceReader = audioDeviceReader;
devices = getAudioDevices(deviceReader)
It seems like the only way to detect if, for example a soundcard is connected, is to restart matlab. I am using a GUI made in appDesigner and also deployed version of it, and restarting takes a incredibly long time. This makes it extremely frustrating to work with the audio application I made, since I frequently need to switch audio devices.
Have I missed something? Is there a way to "rescan" the connected audio devices?

Hi Mattias,
Starting in R2020b, you can use audiodevreset to refresh the list of audio devices MATLAB can interact with:
