Sound clear VI

[Asclepio]

I need to periodically sample about 22 seconds of 44100 Hz, 16 bit stereo
sound using sound blaster (1000000 samples for channel). I use the sound VIs
included in LV 6.0 but after a few acquisitions (without regularity) the
program crashes while executing "sound clear VI" and I must restart Windows.
Does anyone experienced this error/instability ?
I need suggestions for solutions or alternatives, please.

Ciao, Asclepio

please check the buffer size you defined in SI Config.vi, try to change this value, also play with the sampling rate, I think this has something to do with the buffer overflow. Does the program work with the lower sampling rate? There is an example in LabVIEW you can try, it is called Sound Card AutoPower Spectrum.vi.
