Re: Starting jackcontrol gives error
You need to apply the configuration mentioned at http://wiki.linuxmusicians.com/doku.php ... imits.conf and add yourself to the audio group.Raaphorst wrote:cannot use real-time scheduling (FIFO at priority 10) [for thread -1212041536, from thread -1212041536] (1: Operation not permitted)
After changing that file, if i recall correctly you'll have to log out and back in to have them take effect.

Re: Starting jackcontrol gives error
Not to get things working - for this error the 'limits.conf' part should be enough.Raaphorst wrote:do I need to perform the whole real-time kernell fix? like written at http://wiki.linuxmusicians.com/doku.php ... figuration ?
If later you decide you decide you want to tune for improved performance you can revisit that page, but it's not strictly necessary.
Re: Starting jackcontrol gives error
the file limits.conf is not writable. is there an easy way to change this?
and do I need to add these lines to that file? it seems that # means it's a comment-line, correct?

Re: Starting jackcontrol gives error
you need to be root to edit it. Use sudo. And yes, # is (usually) a comment.
