I'm trying to play audio from a multichannel soundcard as per this: https://uk.mathworks.com/help/daq/multichannel-audio-generation-using-an-audio-session.html.
The command on that page:
dq = daq("directsound")
yields
"Unrecognized function or variable 'daq'".
I have the Data Acquisition Toolbox v4.0.1 installed.
Any ideas?

Since it's returning an "Unrecognized function or variable 'daq'" error, my first instinct would be to question the installation of the toolbox. If you type in the command "ver" (see ver), does the toolbox show up as being installed?

daq() was released in R2020a which is vs. 4.1 of the Data Acquisition Toolbox.

ver shows
Data Acquisition Toolbox Version 4.0.1 (R2019b)
So that explains it, thanks.
