After upgrading from Tmaemo7.2 to Tmaemo8.2 yesterday I noticed that my ringtone seemed to be resorting to the fallback setting (the default nokia ring tone). I am using profilesx so I checked the settings there and in the standard settings and everything seemed fine but I was still getting the wrong ring tone. I rebooted and I can't say for sure that was what fixed it but, I am getting my custom ring tone now. I have tested alarms, calendar, and email notifications and they are all working properly.
