| try strace with -r option and check which call takes too long time.
I have tried to run the application with the longest delay (~5 seconds) using 'strace -r' wich is an X-application. Unfortunately, it spills out a lot of text (~2.8 MB). I guess you are not interested in that one.
When I use the application 'play' the delay is only around one second, the strace output is attached below.
Greetings,
Lars.
PS: The file I played is a wav-file containing _only a single sample_ to make sure playing of the file does not interfer with the time measurement.
PPS: The longest time period is this line (~10 lines from the bottom up): 1.687172 rt_sigprocmask(SIG_SETMASK, [RTMIN], NULL, 8) = 0 When I monitor the sound while watching the strace output, I can see that line beeing written half way, than the delay, than the click of the soundcard, then the rest of the strace output.
Attached strace output:
