After a fresh install of Debian Stretch, I blacklisted nouveau driver and installed Nvidia Graphic Drivers throughout this tutorial

before that Debian couldn't detect my HDMI display at all, even when i installed bumblebee but after this, machine detected HDMI display but the sound is still being played over laptop's Speakers which itself is much lower than how it was on windows
I got this output from aplay -l
Code: Select all
$ aplay -l

Is there any idea about it could be fixed?
