Голос музыки не слышен в Ubuntu 16.04 [закрыто]

Итак, у меня в Ubuntu странная проблема со звуком. Я слышу музыку и окружающие звуки при воспроизведении песен с YouTube или Spotify, но в итоге я не слышу никаких голосов.

Когда я перезагружаю компьютер, сначала он работает нормально. Но через какое-то время голос становится тише, и в итоге я его совсем не слышу.

Это действительно раздражает. Кто-нибудь знает, как решить эту проблему?
