Grundinfos zur Konfiguration und Einrichtung einer Soundkarte gibt es hier. Diese Seite ist eher für die Fehleranalyse gedacht.
Bei Problemen mit dem Sound ist es sinnvoll über ein 2. Betriebssystem die Lautsprecher zu testen. Falls man kein Dualboot hat reicht auch eine Live-CD. Aber bitte eine andere Distribution testen . Gentoo basiert eher auf Debian. Daher ist es sinnvoll zum Beispiel Linux-Mint zu testen. Hier gibt es Befehle in der Übersicht um Infos über die Hardware unter Gentoo zu bekommen:
