Default android 4.0 volume problem

Due to galaxyfreak's CyanogenMod 11 RC1 has GPS issue, I installed shekhutanwar and cute_prince's HTC Sense 4.0 Lite rom. It is a stock rom with android 4.0. Everything runs well and no bugs. The question is I can't set the ring volume and notification volume individually. I tried some apps, but none of them works. It seems that it's the the android 4.0's bug.
Did you faced this problem before?
Thank you

for now I just increased my notification file with Audacity.
