sound card application

[Mike_1]

I am programming an audio application in LabVIEW 6i.
I need to record and play simultaneously using
line in and line out. Is there a way to do it using LabVIEW VIs or I'll have to write new sound card procedures in C?
I found exactly the same question in one of the NI Discussion forums two years ago and there was no real answer for that. I hope that during these two years there was some improvement in working with sound card in LabVIEW.
Sincerely, Mike.

Mike,

This may be a limitation of the sound card. I have never tried this, so I can't offer any advice on trying to record and play at the same time.

What I would suggest, instead of spending all that time trying to write C code to do what you need, is to spend a bit of money and either get a second sound card, or better yet, a DSP card. NI has some really good quality cards, and some are fairly inexpensive ones at that. The added benefit is that you get a lot more resolution.

Good luck, I hope that helps.
