Hello I have the same issue. I tried for a couple days to fix it without any results. I have the latest drivers installed (https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS). I then tried to set all configurations to default and ran alsa-info. The ouput is located at the following url and in the attached text document. I hope this is helpful.
