PS: JFTR I'm using linux-rt + rtirq only, there are no shared IRQs, I unbind some USB ports, unload unneeded modules, used different graphics, no unneeded services are started, CPU frequency scaling is set to performance and the sessions run on JWM or openbox. I used both available PCIe slots for the card. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
