Hi, I want to generate some beeps with certain frequency and duration time. Setting "use system alert? (T)" true, I can hear the beep; Setting "use system alert? (T)" false, certain frequency and duration time, I can't hear any sound. Why?attachment is the VI. LabVIEW 8.2.1, WinXP

Your PC speaker only covers certain frequencies.. Mine goes as low as 37 Hz, which I cannot be distinguished from other lower frequencies. I have to go up to 80 Hz before hearing any difference. I can hear up to 14000 Hz and barely 15000 Hz. Now, you cannot compare this with a Hi-Fidelity sound system.. ;)
As for setting False, it will not play anything. So all appears normal.. And of course, if it does not play anything, the duration setting is ignored..

EDIT: I just read the othe people's posts.. The frequency & duration settings work fine on my machine. It is a PC, running Win-XP.
(Finally, I can say something positive about a PC running XP.. ;) )Message Edited by JoeLabView on 08-04-2008 06:13 PM
