nixxx, есть 2 способа ….... не знаю для чего тебе это нужно, так что на выбор
1. Предложенный indeviral — поставить userspace … но частоту нужно задавать в гц
Меняем # cpupower frequency-set --governor userspace (проверить, что получилось)
Устанавливаем # cpupower frequency-set -u 1100000 (проверит, что получилось)
2. Оставить все как было, т. е. intel_pstate ….. но ограничить максимальную частоту
Узнаем # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
2100000
Устанавливаем # echo 1100000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Проверяем # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
1100000

надо политику поменять на userspace

как его заменить на acpi_cpufreq?

intel_pstate стоит по умолчанию

/sys/devices/system/cpu/cpu0/cpufreq/scaling_driver = intel_pstate
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor = powersave

Если не нравится, можно его отключить, добавив параметр загрузки intel_pstate=disable.... и тогда появится acpi-cpufreq c гувернером ondemand … т.е. выводы будут следующие

/sys/devices/system/cpu/cpu0/cpufreq/scaling_driver = acpi-cpufreq
 /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor = ondemand

А вот нужно ли это тебе, лучше почитать топики на эту тему (их было несколько), а лучше потестить и выбрать лучшее ...
UPD .... на всякий случай даю ссылку на Wiki

Так надо было сделать?

Да , наводишь на колонку - CAPTURE и жмешь пробел .

nixxx, то что регулятор уровня записи в alsamixer находится в режиме захвата, а не воспроизведения (как на скрине), вас не смущает?
Тыцните F4.

Так он выключен. Написано же Mute
