Sound Card Control

[Dumbhead]

I am using LabView 8.5 to control a sound card, (MAYA44 V3). The card has 4 Input 4 Out Put. In Channel 1&2 Input, there is a Microphone Preamplifier can be turned on  or off with the sound card control panel. See attached file. In my application, I will need to be able to turn on or off as needed. How can I do it in Labview?

thanks.

Hi there

Is there any API (dll, COM, .NET) delivered with the sound card? If so, use this to do settings. If not, you may want to try DirectX or Windows .NET Framework.

Hi Dumbhead,

Chrisger is right. Your sound card should have come with an API that you can plug into LabVIEW as it supports the Win32 API. Other protocols such as ActiveX and .NET are also supported. If you use another language to control the card, such as C or C++ you can pack your code into a dll and call this dll in LabVIEW using the Call Library Function Node.Hope this helps.
