jackd would not start with -R if realtime permission can not be granted. I
think you would know if there was a problem ;)
I have to say I don't know either what this option is you are setting,
Robin. Is that the granularity of the timer (in u-sec's)? Setting to -1
seems to suggest that the highest possible value is used, although I'm only
wildly guessing. Would be great to know!

cheers,

May I ask what that does? This value is 950000 on my system.
I think jack has rt privileges here on 2.6.28.2 but I'm not too certain=
.
I don't even know how to check that reliably.=
