change sound recording source (line in or mic)

[bimbim]

Hi,

I'm currently doing test on sound and I've found the ones from the examples. It work well but I can't select programmaticaly the input source, mic or line in. I succeed at switching it from windows menus but automation rules...

Can anyone tell me how to change the sound recording line via LabVIEW please?

Can anybody help me to find a solution?

Thank you in advance.

If you search MSDN on multimedia function calls you can find the correct function and DLL to switch. Then use the LabVIEW Call Library node to call this function.

Hi,

I've tried to find something about the dll called in the Vi I attached (based from examples) but as I've never interaced a dll via LabVIEW I'm a little bit lost!

I attached the VI I use and the picture of the volume control (no action on my VI) and recording control (acts on the source oberved in my VI).

I may not use the best way to detect a sound on my PC?

Thank you in advance for your help.

I'm looking forward to your answer.
