USB Microphone DeviceID

[brendan111]

I've got a system with a couple GigEVision cameras and a USB microphone.  Sometimes there are additional IP cameras (axis, etc.), so I used the enumerate cameras function to filter for the cameras I want to use without any user input.  I'd like to do the same for a USB microphone, but I'm not sure what to use.  If I use  Acquire Sound, the configure dialog that comes up lists every microphone and the device ID for that microphone, but I'm not sure how to access that programatically.  One alternative would be if there were a config file that would allow me to set a static device ID. 

Thanks,

Brendan

Hey brendan111, the ability to list audio devices isn't normally exposed through the normal API, but there is a library in Program Files (x86)\National Instruments\LabVIEW 2014\vi.lib\sound2 called lvsound2.llb that includes the following VIs. This snipped will enumerate a list of Input Devices.

Hi CaryChai,

I have a couple of comments:

1) It is always very helpful to post any LabVIEW code you would like help with.

2) It is always better to make a new thread when considering posting question to a thread that ended two years ago.

Feel free to make a new thread and post your question, screenshots, and LabVIEW code there.

OK，thanks.
