I'm having trouble finding a mechanism to record audio from a usb 4 channel audio device. I have found examples scripts that record stereo (2 channel) audio from a usb device, but not 4. Any help would be greatly appreciated.

You need either the DSP toolbox or the Audio Systems Toolbox or (interfacing a different way) the Data Acquisition Toolbox for this to work.

It appears from that it has ASIO drivers, which should in theory be enough for DSP or Audio Systems toolbox, I suspect.

Hi JD,
I work with the Audio System Toolbox team at MathWorks and after seeing this I thought I'd drop a more precise note on the topic.
It looks like your board is recognized by Windows as a standard audio device, leveraging generic DirectSound drivers.
To record more than 2 channels from anything seen by your OS as an audio device (e.g. working with DirectSound, WASAPI, ASIO, ALSA or CoreAudio drivers), you should look at audioDeviceReader in Audio System Toolbox.
I hope this helps.

Never mind - this does work now. I had the wrong driver settings in Adobe Audition to monitor the audio that Matlab recorded.
