Can't change alarm sounds in Gin2JB!

view story

http://forum.xda-developers.com – I would post this in the Gin2JB thread but as I'm a new member I can't post in the development forum! Basically I have Gin2JB which I flashed to v1.8.1. (the latest version) and for some reason I can't change my alarm tone. The stock alarm tone is driving me mad!! I've attached a couple of screenshots to show my sound settings and alarm settings but no option anywhere to change the maddening alarm tone that is causing me to awake with a jolt, throw my phone across the room and sleep in far beyond when I should! I don't want to use a 3rd party alarm app, and I have tried installing a cu (HowTos)
