setup: Ubuntu 13.10 64, 32 GB RAM, i7-4770k. I have tried generic, lowlatency, and rt kernels with the same result. I have disable the ondemand cpu governer. I have changed the settings in Jack in every way. I think my rig is sporting enough power to handle this, especially considering my Arch rig, which is a Phenom II X4 960 with 8 GB RAM never got any xruns.
I have set up and run the perl tool from https://github.com/raboof/realtimeconfigquickscan. It only complains about a few things. My swappiness, which I am assuming is not the issue since I have loads of RAM. Also, it report that it finds the "noatime" parameter. That's it. Everything else is good.
So what is going on? Please help. Thank you.
