Has anyone figured out what to do, to got speakers from Y550 work properly in Linux? I've spent some time trying to do ALSA work good, but still I've got only 2.0 speakers working.. Can't persuade subwoofer to do his job.


There might be multiple solutions depending on the Linux kernel you are running on your system 


Solution 1






options snd-hda-intel model=lenovo-nb0763


at the end of /etc/modprobe.d/alsa-base.conf




Or Solution 2


2) Installing Kernel version 2.6.34 and above should fix the issue 





Or solution 3


3) Install ALSA version 1.2.23
