i have the same issue i have with every rom i have tried with the exception of apex and squidlyrom where when i setup custom ringtones for individual callers they always go to the default ringtone. I thought about it last night it might be because apex and squidly allows me to use the stock moto dialer instead of the asop one.
I am using the free app ringdroid available on the android market to make my custom ringtones is this the reason why none of the roms that doesn't use the blur dialer causes it to always ring with my default. As an idea i even used root explorer and deleted all the stock ringtones and then pasted my custom ones and it will work every once in awhile.
What app does everyone else use to make custom ringtones out of mp3s on this rom cause obviously ringdroid isn't compatible with the d2 unlike my og droid where it worked with every rom i tried flawlessly. I'm diggin this rom and would like to resolve this issue once and for all.
