Re: [LAU] usb soundcard: xruns and latency even with -rt kernel

It seems to be a relatively blunt tool for invoking chrt -- in my case, it finds an internal sound card that I don't care about and also a few other usb-related interrupts that don't need to be on high priority. It does, though, also increase the priority of the rtc and i8042 irqs, which I hadn't been doing. So now I'm (manually) setting rtc highest, followed by the irq for the usb bus my soundcard is on, followed by the two i8042 interrupts. It hasn't seemed to help, though. Here are my HPET and timer settings. They -look- correct to me, though I'm not really sure what they all mean. Is there anything else I should look at?
