Geen subwoofer en center geluidskaart ubuntu 20.04

(1/1)

Niwde789:
Ik heb een geluidskaart Creative Labs Sound Blaster Live 5.1 EMU10k1.  Pavucontrol staat op analog surround 5.1 output + analog stereo input. Alsamixer center en lfe geactiveerd.
Toch is er geen geluid uit de center box en de subwoofer. Zonder bas klinkt het blikkerig. Bij het testen van de speakers komt het geluid van front center uit de speaker links voor en het geluid van de subwoofer uit rechts voor. Wat zou dit kunnen zijn?
