If you should start your audio sessions by scripts, you e.g. could add
if [ "$(grep -v performance /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor)" ]; then
echo -n performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor >/dev/null
fi
this is independent of the tool used by your distro, so no wrapper or
other trick is needed, if you run your session on another machine. I
first check, if it's already set up to performance, because I use sudo
with a password and I won't type the password all the times I restart a
session, while the governor already is set up to performance.
