Hi again Raymond. Sorry to bump this thread without further progress - but I don't know how to follow your instructions. Is there any chance you can elaborate?

It is a re- badged Clevo W250ENQ. The sub-woofer functions fine in Windows (which I have since removed), but doesn't work in Ubuntu. speaker-test produces pink noise for the left and right channel, but nothing for LFE (the sub-woofer). There's a greyed-out sub-woofer volume slider in the pulseaudio widget (see attachment), but I think this might be a red herring. I've tried adjusting/unmuting all the channels in alsamixer, but doesn't seem to do anything. The module I'm using is snd-hda-intel and the codec is VIA VT1802.
