Stephan bedoelt de volume knoppen op het toetsenbord van de laptop. Ik zie hier in de Lenovo T410 specificaties, dat deze "individual speaker volume up, down, and mute buttons" heeft. Ze zitten links van de ThinkVantage knop.
Verder zou ja van deze Ubuntu Sound Trouble Shooting stap 1 t/m 6 kunnen doorlopen. Voor stap 1 kun je het beste het terminalvenster groter maken. Nadat je
pacmd
[Enter]
hebt gedaan verschijnt deze prompt >>>
Daarachter typ je
list-sinks
[Enter]
Die output zou je hier kunnen posten. Je keert weer terug naar de standaard prompt via commando
exit
[Enter]
Met stap 2 test je het geluid in het terminalvenster.
>>> list-sinks > list-sinks-T410.txt
1 sink(s) available.
