Comment 24 for bug 94566

I found solution that works with Amilo Pro V3515 (Fujitsu - Siemens).

You have to add 2 lines to your /etc/modprobe.d/alsa-base file

#add this lines
options snd-hda-intel model=3stack enable=yes
options snd-hda-intel model=auto position_fix=1 enable=yes

and restart laptop. I hope it helps.
