at the very beginning sound was working using the motherboard `line out` jack.
A few days ago the motherboard `line out` jack went bad. The sound is awfully robotic and unintelligible. The jack on the case front panel gives no sound at all (I hadn't tried it before, because I was using the motherboard `line out` on the back).

Computer is 3 weeks old:

I've tried many things: pavucontrols, reloading/restarting alsa and pulseaudio, adding lines like `options snd-hda-intel model=auto`, installing graphics card driver but nothing seems to work.
