Why is there no beep. Playback of waves works fine, LabVIEW 8.5

[jonidas]

Hello Everyone,

I have a problem in LabVIEW 8.5. I have set up my programm, most things already work fine. Except one thing recently decided to quit on me: the beep.vi.

In my main VI there are wave-files being player which works fine, some data is read .... not interessting. And at a certain cue the beep is supposed to heared. But I don't hear it, except if I set the system error sound to true. In that case I can hear the systems error sound when the cues comes up. But if I set it to, let's say 440 hz and 500ms I can't hear anything.

Has anyone an idea what the problem might be? I am pretty much out of ideas ...

Thank you very much

Bye

Jonas

I assumed the Beep used the system speaker, which most new computers dont have. Many have a small buzzer, else the sound card is used for playbacks. That'd be an explanation, but it's only an assumption/theory.

But the system alart sound, which I can hear is being generated through my speaker. Or do you thing that the system alarm sound come from the speaker while the manually configures sound comes from the systemspeaker?

[Yamaeda]

If it is a buzzer of sorts the frequency range is quite slim. Do you get a "real" sound, a "ding" or a "Brrr"?

(still in theory mode)

From what I can gather from the help file, all parameters are ignored.  This leads me to believe that it USED to make a buzz on the internal speaker, but now it plays the default "ding."  Did you happen to change themes or something that maybe made your default system sounds get overwritten?

[Edit] I did a quick search on "beep.vi" and it tells me that you'd be better served paying a wave file.  😉
