I have noticed that when I'm plugged into my computer with the usb cord my notifications wont sound, it just vibrates. the phone will ring if there's a incoming call but no other alerts will work? any ideas, ive checked all the settings and all looks in the norm.
Tied a soft reset, was no help.

Try checking the Settings/Sound/Notification ringtone setting also remeber that you do not get a notification alert from phone if you have it set to Mass Storage.
