Win7 and sound

#1
I had complained that TCC's BEEP (and WIN32's Beep()) were much louder than the Win7 system sounds.

With both Windows\Media folders open (XP's and Win7's) I compared the two sets of WAV files (with mplayer). In that test, the Win7 sounds are indeed much quieter, perhaps enough so to account for my complaint. Can anyone verify this? If I set the volume to where BEEP is reasonable, I can't hear the system sounds.

Are the system sounds and Beep() produced by different methods? Should I have a way of changing their volumes separately? I don't; I have only a simple volume control with two sliders "Device/Speakers" and "Applications/SystemSounds".
