Ubuntu – Lenovo Y50 Subwoofer does no work with Ubuntu 14.04.2 LTS


I could not get my Subwoofer on Lenovo Y50 to work. Googled around and did not find any solutions. Let me know if anybody has any clue. Thanks!

This is what worked for me:

first, install and run HDA Analyzer:
wget -O run.py http://www.alsa-project.org/hda-analyzer.py
sudo python run.py (root is required)

second, using the gui do this:
•PIN 0x17 -> Widget Control -> Check OUT and Uncheck Mute:

•PIN 0x1a -> VREF -> Set it to 100:

And third, test it by listening to some music.
If it still isn't working, you can follow this thread, maybe someone will find an answer:

HDA Analyzer can be found here: http://www.alsa-project.org/main/index.php/HDA_Analyzer
