I was describing a problem in the Multifunction DAQ board, but it looked like software had a part to play too.
Basically, I was running a sine generator VI through analog output to a speaker, and experienced a sudden break or phase skip in the output. It's not a particularly rare occurence, and I'm hoping I can eliminate the problem as a source of error for my experiment.
Are there any ways to prevent the skips?
I'm using Labview 8.6 on a PXIe-8108 controller, recording through PXIe-4498 and outputting through PXI-6733.
