There is always an xrun produced when jackd starts up. Jackd intentionally ignores this, you have to comment out some code to see the report. I was never able to figure out what causes this xrun. I did establish that the duration is always about the same, depending on whether NPTL or linuxthreads is in use - in one case it was 70 ms or so, in the other 30. Lee
