Nothing has got rt priority. Are you sure that you are running the lowlatency kernel? If not, than you need the boot option 'threadirqs'. What's the output of uname -rm Before you boot the lowlatency kernel or a generic kernel with boot option 'threadirqs', make USB the head and remove the keyboard from this list, IOW change it to RTIRQ_NAME_LIST="usb snd". _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
