Нет звука HDMI на ubuntu 17.04
У меня возникли проблемы с получением звука из моего HDMI-соединения (в Windows это работает). Звуковые опции даже не отображают HDMI как возможный выход, и даже pavucontrol показывает все HDMI-устройства как отключенные.

Я также попытался добавить в alsa-base.conf следующие два параметра (отдельно), но без эффекта
options snd-hda-intel index=1
options snd-hda-intel model=pch position_fix=1
