Problem with continuos sound input

[depa981]

Hi, I'm trying the continuous sound input example in labview, my problem is that whenever I try to run the VI the graphic of the sound acquired is empty, I just get a flat line with value 0. I even tried to use an external microphone but the problem persists. Does anyone have any suggestion? Thank you

Do you get any errors while acquiring sound data? (Might be a problem with sound drivers.)

Or does the VI run without any errors and just outputs waveforms consisting of just "zero" values? (Might be a problem of the mic or the sound input circuitry of your computer.)

I get no errors, the VI runs correctly but nothing is displayed on the graph, just a flat line at 0

Hi depa,

so test the mic using other software (like e.g. Audacity).

Please also check you are using the correct sound device in case of multiple mics!

Hi, thanks for the suggestion, I just tried with audacity and everything works fine, it seems that the problem is only with labview. I really don't know how to deal with the issue.

Me neither as I cannot test with your computer...

I tried with the 2019 version of labview and it's now working
