Hello all, Im hoping that you can help me with a problem Im having with jack and PD. I am running jackd from qjackctl in realtime with a 64 frame buffer (Hammerfall HDSP multiface: 2.67 ms delay). I am using PD, and after both have been running fro about 20 min I get a ton of xruns. (and as an xrun has negligable weight, that is a lot of xruns) I got through my logs and can find no reason for this when cross-referencing by time of occurance. Here are some possible unrelated errors, or perhaps they are leading to my problem... >From System Logs: Failure registering Root Plug module with the kernel Failure registering Root Plug module with primary security module. >From Kernel Startup Log: PCI: Using ACPI for IRQ routing ** PCI interrupts are no longer routed automatically. If this ** causes a device to stop working, it is probably because the ** driver failed to call pci_enable_device(). As a temporary ** workaround, the \"pci=routeirq\" argument restores the old ** behavior. If this argument makes the device work again, ** please email the output of \"lspci\" to bjorn.helgaas@xxxxxx ** so I can fix the driver. My system is: (http://www.aproximation.org/application/AMD64laptop.html (old)) AMD64 laptop Hammerfall HDSP multiface and cardbus Fedora Core 3 test 1 linux-2.6.10-rc2-mm1 kernel What does the priority selector mean in qjackctl setup? I just leave it at 0. Any help would be greatly appreciated! I would LOVE to get this machine running jackd flawlessly. Thank you for your time! -thewade
