It is incredibly loud and annoying lol. I am using Windows XP SP3 and ActiveSync 4.5. I've gone to Control Panel -> Sounds -> turned off the sounds for ActiveSync "Connect Confirm" and "Disconnect Confirm" but now I get the even more annoying PC beep instead. The notification sound for ActiveSync is also unchecked on my TP2. I tried muting the "SW Synth" from my PC Volume Control but that didn't work either
Any suggestions?
