I solved it.

1.SET CPU frequency scaling

Code

#append to ~/.config/autostart.sh
 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
