concerning the first point, I did some measurements... the file I used has a length of 1488 ms trigger start jiffies=7466937 trigger stop jiffies=7468172 difference = 1235 (1235 ms) pcm prepare jiffies 2=6761125 trigger start jiffies=6761126 trigger stop jiffies=6762361 difference = 1235 (1235 ms) trigger stopped, buffer empty, stop decoder jiffies=6762684 difference = 323 (323 ms) so I was wondering, why the difference between trigger start - stop is not 1488ms but 1235ms. I still guess that it may is a wrongly updated pcm pointer?
