Problems with Data Adquisition using DirectSound

I got an error, "Audioinput" not supported in this device, but no problems with AudioOutput.

Thank you for the info, but I need to use DirectSound form Data Aquisition Package, not from C++

I don’t have the Data Acquisition Toolbox, so I have no experience with it. I’m also not certain what you’re doing.

However a brief dive through the documentation reveals Multichannel Audio Input and Output (link) in which is:

• You cannot read directly from or write directly to files using the multichannel audio feature. Use audioread and audiowrite.

Basically, the toolbox has bugs, leading the examples can not be reproduced.

The step dq = daq("directsound")will get an error message
