[HELP]HTC volume control and ring type conflicttion!

[lihaokingkong]

Hi guys,now I got a problem on my Srpint TP2. I use "Vibrate and Ring" as my ring type,but every time when I set vibrate or silent using the volume control,then turn the volume on again,my ring type would automatically be changed to "Ring" but not "Vibrate and Ring". And every time when I make a soft reset,same things happen,my ring type would automatically be changed to "Ring" also. So I think there's something wrong with my rom,seems there's a confliction between system and the HTC volume control.

Anyone knows how to fix it??? Or how to tweak the registry to make it well???
