  • I solved it.

    1.SET CPU frequency scaling

    1. #append to ~/.config/
    2. echo performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor >/dev/null

    2.Tuning USB devices for minimal latencies

    use the module configuration line (e.g. in ~/.config/modprobe/modprobe.conf):

    options snd-usb-audio nrpacks=1
