sound input read multiple soundcards

[Carneoleon]

Heey everybody,

I have a problem. I want to read two different signals at the same time from 2 different soundcards. 1 internal soundcard from my laptop, and 1 usb soundcard. 

So i used the Acquire Sound VI.

Reading both signals at the same time is not a problem until i set the measuring time to about more that 30 seconds. It gets a buffer overflow.

So i tried to do the following:

I first made this with 1 signal first, and it worked perfectly, every second it got updated.

But, when i added the second signal it only wanted to read the first second of the first signal and then it got stuck, and i had to stop the software by closing it. And then killing labview with the taskmanagement thingey from windows.

Anyone have any idea what the problem is?

Greetings,

Jory

Ok, never mind, i've solved it. I made the buffers larger (at the sound input configure block) and now it works like a charm 🙂

edit:

ok it is just needs to make longer the data aquisition in the number of samples to aquire.

This message is quite old but let's try... I can't find the buffer size on the configura audio input.

can you please explain it? regards.
