Hello,

I am trying to run the app in the link:

In step 2:

2. Use the default settings of the app and click Capture. Make sure the device name and the channel number match your system's configuration.

I tried on three computers but there is no default setting. Please see my attached pic. Can you please help me with this issue.

Thanks,

Hi,

It looks like audio device hasn't been detected. There is a "No full duplex audio device detected" message under the Audio Device drop down.

The supported drivers for audioPlayerRecorder are platform specific:

• Windows — ASIO
• Mac — CoreAudio
• Linux — ALSA

If you are using a Windows machine, the app will require an ASIO driver. You can download this driver from the following website.

Once you install this driver, you will need to restart MATLAB. You will be able to see the driver in the drop down menu once you open the app. And then you can see default values set for all the fields
