"Simultaneous Sound IO.vi" LabVIEW 6.0 Example DOESN'T work

[kjtc]

After running this example I get this error:
*********
Error -10408 occurred at SI Config.vi in
Simultaneous Sound IO.vi.

Possible reasons:
NI-DAQ LV: The specified channel is in use.
**************
The example says that on PC you'll need two sound cards (I only have one) but I have seen it running in a laptop that has only one sound card. Maybe it is because this laptop runs under Windows 2000 and my machine runs under Windows NT 4.0.

Hello,

This example is not designed to work on a PC with only one sound device. I do not know how you were able to get it to work on a computer with only one sound device. Perhaps the laptop had an additional sound device built-in of which you were not aware. At any rate, I don't believe the operating system would have any effect on this VI...if you look at the VI documentation, it states that the example will work on a Macintosh that has only one sound device, but a Windows PC would require two devices. I ran the VI on my computer (which only has one sound device), and although I did not receive an error, I also did not receive any sound output...only sound input, since I only have one device.

I hope this answer sheds some light on the situation for you. I wish y
ou luck with your application, and I hope you have a pleasant day.

Sincerely,

Hi,

I have had this example running and not running on different computers.
I believe the differences is if the sound card is a PCI or ISA bus type.
The older ISA bus types are slow and don't handle full duplex very well.
