Beskrivelse

Scriptet ændrer hvilken lydudgang der benyttes som standard.

Ændringen tager først effekt efter genstart.

Parametre

Aktivér: Sæt hak hvis du ønsker at sætte standardlydudgang. Udelad hak hvis du ønsker at nulstille til standard. Standardlydudgang: Navnet på den lydudgang (i lydsystemet pulseaudio kaldes dette en “sink”) der skal sættes som standard. Du kan finde navnet på alle lydudgange ved at køre scriptet: “Lyd - Udprint informationer omkring lydenheder”
