My first question is: It there a way to check if realtime is really working? I am running demudi 1.3 with what others have confirmed is totally adequate hardware. When I first boot demudi I can start jack with the following command: /usr/bin/jackd -v --realtime -u -dalsa -dhw:0 -r96000 -p256 -n2 I would like 96000 in order to create high quality DVD audio. But when I login to fluxbox and qjackctl, gkrellm and other apps start I see output in qjackctl's display like this 1(4532) after about 30 seconds. I then go back to the command line and I willsee the following repeating on the command line very fast: delay of 2810.000 usecs exceeds estimated spare time of 2664.000; restart ... delay of 2810.000 usecs exceeds estimated spare time of 2664.000; restart ... delay of 2810.000 usecs exceeds estimated spare time of 2664.000; restart ... delay of 2810.000 usecs exceeds estimated spare time of 2664.000; restart ... delay of 2810.000 usecs exceeds estimated spare time of 2664.000; restart ... delay of 2810.000 usecs exceeds estimated spare time of 2664.000; restart ... and on and on...... After this I cannot get jack to respond properly unless I kill all apps running in fluxbox and don't pull up the menu in fluxbox. Even simple mouse commands to view the fluxbox menu cause xruns! - I have used Ingo Molnar’s 2.6 kernel patch (I am having the same problems in the default 2.6 kernel with demudi 1.3 with kernel 2.6 and do not remember these problems with demudi 1.2.1 kernel 2.4) - I have set my Audio Card priority to 99 (also tried as default) - I have set my jack priority to 70 (toggled between 0 and 70) - I have installed and configure realtime-lsm (played with all parameters) - I have put export LD_ASSUME_KERNEL=2.4.19 in my /etc/profile What else can one do to solve this problem? I am stumped! Thanks Chris Cherrett
