звук никогда не работал на Lubuntu 18.04.3

Спасибо за вашу помощь, я пытался решить мою проблему в течение нескольких недель безрезультатно. Единственный способ получить звук - подключить наушники. К сожалению, у меня их больше нет.

Это компьютер, который я сделал из разных частей, которые я купил. Моим единственным выходным устройством была гарнитура Hyperx Cloud , которая больше не работает.
Операционная система: Lubuntu
Графика: Radeon RX 580 Dual OC 8GO
Процессор: Ryzen 5 2600
Материнская плата: asRock B450 pro4

Мой экран dell P2210 один, кажется, нет внешнего звука.
Я просто подключил обычные наушники, которые работают, но мне нужен более громкий звук; возможно, мне стоит купить набор внешних динамиков?

Вот несколько выводов, я не уверен, как их читать Выход для sudo lshw -c sound:

При использовании pavucontrol, я могу настроить звук вверх и вниз, но я никогда не слышал этого.

Что мне теперь делать? Я чувствую отчаяние

Спасибо за любую помощь
