Some remarks though: * Is /dev/rtc the kernel timer? I thought it was the device node for access to the real-time clock. I don't even think it's necessary to prioritize it anymore because most applications use the kernel timer: http://wiki.linuxaudio.org/wiki/system_configuration#hardware_timers I'm far from an expert on timers so I could be wrong, I still find this a bit of esoteric stuff. * Using setpci in this context is deprecated unless you're still using am machine with a PCI bus which I highly doubt: http://wiki.linuxaudio.org/wiki/system_configuration#pci_bus_latency Regards, Jeremy _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
