Ich habe gerade Lenovo U430p bestellt und Ubuntu 14.04 installiert. Alles hat wunderbar funktioniert, außer dem Ton. Obwohl der Ton funktioniert und vom System erkannt wird, ist der Ton im Vergleich zu Windows 8.1 (ist vorinstalliert) sehr leise.

Antwort1
- Ihr Hauptton ist der zweite (der erste ist HDMI-Ton), installieren Sie also „Pulse Audio Volume Control“ aus dem Software Center (oder
sudo apt-get install pavucontrol) und starten Sie es über das Multimedia-Menü. - Gehen Sie auf die Registerkarte „Ausgabegeräte“ und stellen Sie die Lautstärke für das letzte Gerät ein.
- Das Ändern des Profils im letzten rechten Tab kann hilfreich sein.
- Sie können die Lautstärke auch starten,
alsamixerindem Sie in einem Terminal die Taste F6 drücken, um die zweite Karte auszuwählen, die Pfeiltasten rechts/links, um den Fader auszuwählen, die Pfeiltasten auf/ab, um die Lautstärke einzustellen, und die Taste m, um die Stummschaltung ein-/auszuschalten.
