Нет звука / фиктивного вывода 18.04.4 на новом Dell G3 15 3590 с предустановленной Ubuntu, Аудиоустройство: NVIDIA

После обновлений с Ubuntu 18.04 до 18.04. Я новичок в Linux (раньше использовал только Apple) и не инженер, поэтому я пытаюсь быстро узнать, как работает Linux Ubuntu, и прочитать о многих решениях для похожих проблем, но не смог найти точно такую ​​же проблему и правильный еще не ответили.

Может, кто-то здесь может мне помочь ??

Что я выяснил до сих пор:

Пока звук еще работал, он показывался в настройках: speaker-sof-skl_hda_card и цифровой микрофон-sof-skl_hda_card

Что я обнаружил, так как оно больше не работает:

Аудиоустройство: NVIDIA Corporation GP107GL High Definition Audio Controller (rev a1)

В настройках / обновлениях дополнительные драйверы:

• Корпорация NVIDIA: неизвестно

• Устройство использует рекомендуемый драйвер: Используется драйвер NVIDIA Metapackage nvidia-driver-440 (проприетарный, протестированный)

• Корпорация Intel: неизвестно

• Это устройство не работает: * не используйте это устройство

• Intel Corporation: неизвестно

• Это устройство использует альтернативный драйвер:
• Используются дополнительные файлы для включения Intel DMIC audio von oem-fix-audio-intel-dmic (с открытым исходным кодом) )

Я попробовал терминал и
