Hi,

You can use audiodevinfo function for listing all types of input available for the computer.

If you would like to explore more about the function you can refer to the link mentioned below:

Hello,

uidropdown consists of several useful properties for your question, Values, Items, ItemsData. You should collect device information with audiodevinfo whose output is a structure with input and output devices.

info = audiodevinfo

You can populate dropdown Items property with corresponding Name property

dropdown.Items = {info.input.Name}

and corresponding device IDs

dropdown.ItemsData = [info.input.ID]

So, when you need to provide ID for the selected device, you can use the Value property of dropdown to obtain it.

When dropdown is populated with ItemsData, Value of the dropdown is the one associated with ItemsData.
