Open a console ("monitor and sea-shell"-button in KDE taskbar) and type:
Open the outputted file, type:Code:lspci -v > pcidevicelist
Paste the part about your soundcard here in this forum.Code:kate ./pcidevicelist
btw, what's the exact problem? Have you tried opening the KDE configuration center and fiddling with the sound settings ("sound and multimedia" -> "soundsystem")?
