Automatisches Standby bei Creative Labs GigaWorks™ T20 Serie II deaktivierbar?

I've created an audio file with really low frequency tone. You can use any audio editing application to generate that low frequency tone. So it's a 3 sec WAV file 11kHz/16bit/mono containing a 10Hz tone with fade in and fade out to avoid clicking. This tone is low enough for this kind of speakers won't play it at all (I believe, it's gonna be filtered actually), but they'll hear it. Anyway, you're not gonna hear it.
Then I've googled a VB script for a background audio playback.
Looks like this:

Set Sound = CreateObject("WMPlayer.OCX.7")
Sound.URL = "WakeupHum.wav"
Sound.Controls.play
do while Sound.currentmedia.duration = 0
wscript.sleep 100
loop
wscript.sleep (int(Sound.currentmedia.duration)+1)*1000

It has to be saved as .vbs file and launched with 'wscript.exe' to produce no any UI at all.

And what would you think I did next? Obviously, set the Windows Task Scheduler to run that .vbs file each 10 minutes.
Actually, it may stop your PC from auto sleeping, I'm not sure, I don't use it, only auto screen off.
Also, setting schedules is Task Scheduler is pretty much flexible, so you can set it run for a day, but stop waking up the speakers at late evening.
