After installing a graphics card, I cannot get the sound output to work anymore.
I initially thought it would be a bios problem
(https://askubuntu.com/questions/18417/no-sound-after-installing-a-new-graphics-card)
but there aren't any settings I haven't tried to modify already.
Is there a chance to find the old internal sound "card" from the main board
that I have been using before installing the GPU?
