Comment 6 for bug 191086

Could you attach some files for us?

The result of cat /proc/asound/cards

uname -a > uname-a.log
sudo lspci -vvnn > lspci-vvnn.log
dpkg -i linux-ubuntu-modules-$(uname -r)

Could you go to https://wiki.ubuntu.com/DebuggingSoundProblems and run the automated sound information collection script?
