You already used a kernel with threadirqs, a RT kernel could improve things, but can't do magic. What distro are you using? Perhaps the distro provides a "better" kernel. Did you already rule out other culprits? Shared IRQs, frequency scaling, BIOS settings? Are you using rtirq? If so, did you check the status? _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
