I have been trying to solve this problem for a number of months now and have tried countless CAT variations. No skin sounds can be heard without use of skin.

In fact I went to extremes today and installed a whole new sense ROM android 2.3.5. I installed Nuance for TTS and tried various voice files. No joy. Then installed Loquendo, still no joy.

It is something that I can live without but yet I lose sleep over it. Why?
