Thanks for your reply. I tried both these suggestions but none of them worked.
My Alsa info is located at http://www.alsa- project.org/db/?f=661aa91faf8c9cf4b6b7726b0a3cceefab46876b >From windows 7 I found out that realtec ALC662 codec is located at location 0 on HD Audio bus. But as alsa-info shows, system does not detect any codec at that location. Is it possible to know whether windows driver finds codec at location 0 by usual method or it has some workaround for this bug?
