I am having a similar problem. I am using vetvitos black pill and photo contacts pro. For some reason SMS tones aren't working with that combo. I do get ring tones to come in, but that's it. (sorry can't help!)
Its a 5067 issue as far as sound droping randomly on sms and requiring reboots as far as I can tell for me. My same builds on 5060 have not exibited these symptoms.
