Please review. Impact to PA: This patch will enable PA with volume ramping feature. People use IPhone may have this kind of experience that when a telephone call comes in when user is listening to music, the music is gradually volume down to mute; and after the call, the music is gradually volume up to previous level. This patch will give PA the ability to do the similar thing, and I have tested with this patch, the effect is as good as IPhone. Two API is exported for this feature: void pa_sink_input_set_volume_with_ramping(pa_sink_input *i, const pa_cvolume *volume, pa_bool_t save, pa_bool_t absolute, pa_usec_t t); void pa_sink_input_set_mute_with_ramping(pa_sink_input *i, pa_bool_t mute, pa_bool_t save, pa_usec_t t); What's included in this patch: 1, Fixed various bugs in envelope.c 2, Added logic in sink-input.c for volume ramping Calculation formula is in the comments for the code, so I don't explain in this mail, please check the code. Thanks!

I began work on the enveloping stuff a while back but never actually made use of it anywhere in PA. Can't work on everything at the same time, sorry. It's going to be enabled when it is going to be enabled. Sorry, but there's nothing more definite I could say. Always happy to take patches! If you want something to happen the best way is always to do it yourself!
