Звук не работает в Dell XPS all-in-one 2710 с Ubuntu 16.04

Технические характеристики

Звук из моих динамиков не работает по умолчанию, пока я не установил QasMixer или GNOME ALSA Mixer .

Когда я открываю gnome-alsamixer, я считаю, что динамики не отключены, а наушники отключены. Если я делаю наушники беззвучными, динамики работают, но я должен делать это снова каждый раз, когда я запускаю компьютер.

Ниже приведен вывод lspci -nnk | grep -A Audio и aplay -l и pactl list sinks [ ! d7]
