alsa: make defines for smoother configuration
Make new defines for the smoother window size and adjust time constants instead of reusing some unrelated constant. Increase the smoother window size even more because the bigger it is, the better. Since we have a 200ms max update interval and the max smoother history is 64 entries, 10seconds is a good default. Decrease the smoother adjust time to 1 second. The previous value of 4 seconds was too much to adapt quickly after a resume.
