I suspect that this chipset isnt always being detected correctly by the kernel. I have completely gotten rid of these problems on 1 machine thats using this module.. vastly improved another and got a 3rd working perfectly from no RO sound at all with playing with the model= parameter of the snd-hda-intel module.

In the case of my laptop the best get was " options snd-hda-intel model=lenovo-sky "

Other may want to look into other options or perhaps try one of these:

/etc/modprode.d/hda-intel.conf

# Only use 1
#options snd-hda-intel model=3stack 
options snd-hda-intel model=3stack-6ch 
#options snd-hda-intel model=3stack-6ch-intel

Or you can use this script to gather info about your soundcard and find a models= option that better suits your actual hardware.

~/alsa-models.sh

#!/bin/bash

## Changed this if needed
EDITOR=gedit

mkdir ~/tmp-alsa-info
cd ~/tmp-alsa-info
wget -q http://www.alsa-project.org/alsa-info.sh -O ./alsa-info.sh
chmod +x ./alsa-info.sh
./alsa-info.sh --no-upload --output ./alsa-info.txt
cat  /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz  |gunzip >./HD-Audio-Models.txt
$EDITOR ./alsa-info.txt ./HD-Audio-Models.txt
cd ~
sleep 2
rm -rfd ~/tmp-alsa-info

chmod +x ~/alsa-models.sh
~/alsa-models.sh


This will gather the info and open the needed documents.
