Нет звука после обновления alsa

Я новичок в Linux, но очень люблю Elementary за его простоту. Заметив, что мой звук в Elementary был довольно плохим, по сравнению с Windows 8.1, я попытался обновить драйверы звука. Я закончил тем, что загрузил один отсюда, но после перезагрузки мой значок звука исчез с панели инструментов, и звука не было слышно. В настройках> звука я вижу «Dummy Output» и бегом alsamixerговорит cannot open mixer: No such file or directory. Я гуглил безуспешно, и многие предлагают, sudo alsa force-reloadно это возвращается

Unloading ALSA sound driver modules: (none loaded). Loading ALSA sound driver modules: (none to reload). 

Я потерял надежду, и я надеюсь, что кто-то здесь может помочь. Я удалил драйвер, который я ранее скачал по ссылке выше (может быть, остались кусочки?), И удалил заново, установив alsa-base и pulseaudio, но я до сих пор не вижу значок звука или воспроизведение звуков.

Любая помощь с благодарностью.
