Yast Hardware Sound
other button - Volume - Master & PCM slider set to 70%

Open kmix’s mixer window. Pick Options/Settings, channels, check all and see what happens if they are all at full blast. Uncheck all recording options first and see to them when needed.

You could also try alsamixer from a terminal window. That will show all sliders available for your card.
