Public bug reported: When the external sound card (SB Live! 24 bit) is used, the volume slider and the mute button have no effect. The volume is low. I tried two SB Live! 24 bit cards (at home and at work). The behaviour is the same. On Lubuntu 20.04, there was no problem.
The embedded sound card operates normally and reacts on the volume slider.
