clear;
daqreset;
dev = daq.getDevices
session_snd = daq.createSession('directsound')
sndID = dev(3).ID
ch_snd = addAudioInputChannel(session_snd, sndID, 1)
I am trying to use a sound interface using the daq tool box. I wrote the following code for a preliminary test, but encountered the error in the title. I cannot find out what this message means. Could anyone help me to solve this problem?

Your code pulls out sndID from device 3, but we do not know that device 3 is the same as the directsound device.
We also do not know that any directsound devices were found or that there are any channels available if they are.
The error hints that the driver for directsound was found but no devices with it.
