On a non-RT kernel. 512 and 3 periods at 48K is not such a setup as the OP wants and we were not arguing about non-RT kernels, we were arguing about non-rt priority, you could use a generic Ubuntu kernel with 'threadirqs' to get rt priority for USB devices. The lowlatency kernel is a non-rt kernel, too, just with minor configuration changes, for the official lowlatency kernel e.g. 'threadirqs' needs not to be added to the boot line options. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
