Dear Maintainer,

The problem exists from the fresh installation of Debian, the sound is tinny and no low frequencies are 
reproduced (checked with youtube 20-20000 Hz video). Googled for a solution, found hundreds of similar reports
for this laptops and other models having 2 pairs of speakers. The suggested manipulations with 
HDAJackRetask did not help. Installation of pulseaudio did not help too. Alsamixer from alsa-utils package shos 00 for 
LFE and does not allow to change volume.
