Can you explain a little more what you're trying to do? You shouldn't generally need to worry about volume scaling in PA modules. But ultimately PA scales volumes between PA_VOLUME_MIN (aka 0%, aka -inf dB) and PA_VOLUME_NORM (aka 100%, aka 0dB) typically, but really the upper volume is PA_VOLUME_MAX (aka Lots%, aka +Lots dB). But if you explain in a bit more detail we can probably advise you better. I don't think you'll need to do any specific volume handling unless you are writing a very specific module.
