Two problems with trying your VI: I do not have the Sound & Vibration Toolkit so two VIs are missing. I do not have your hardware so I cannot acquire any data.
Put an indicator on the array wire at the input to the filter. Run your VI so that data is present. Then Make Current Values Default and save. Post that VI.
Have you placed indicators or probes on the outputs of the filter and scaling VIs to see whether any data is present and waht it looks like? Do you get any errors? The filter VI has an error output but it only returns an error code, not the full error cluster. Automatic error handling (if you have it turned on) will not catch those errors. You need to wire an indicator or Error Cluster from Error Code.vi to see if there is an error.
Often errors like that are from not setting the filter parameters correctly.
