Show the available audio devices. Then, connect a device, refresh the list, and show the updated list.
audiodevinfo with no inputs to view information about the
input and output audio devices on a system.
audiodevinfo returns a
structure containing two fields,
>> info = audiodevinfo
info = struct with fields: input: [1×1 struct] output: [1×1 struct]
Show the names of the available output audio devices.
ans = 'Built-in Output (Core Audio)'
After plugging in an audio device, refresh the list of available devices and get information about all devices.
>> audiodevreset >> info = audiodevinfo
info = struct with fields: input: [1×1 struct] output: [1×2 struct]
Show the names of the available output audio devices again, including the new device.
ans = 'Built-in Output (Core Audio)' ans = 'HDMI (Core Audio)'
If you rename an audio device before refreshing the list of devices, the new name of the device will not appear in the list. Instead, its previous name will be displayed. To update the name of the device in the list, you must start a new MATLAB® session.
