Debian Wheezy and Lenovo G50: setup sound card

One of the problem I have after debian installation is that it seems controller and sound card seems to be recognize.
Giving the commands:

lspci | grep audio
lsmod | grep snd
speaker-test  
 
may help you to see what has been recognized.
In my case all seems to be recognized, but I hear no sounds.

From gdm right-clicking up on the right, on the volume control and choosing sound preferences I see only this voice:
Built-in Audio Digital Stereo(HDMI)
and above in the combo menu list I see only
HDMI / Display port

This not give me assurances.
So after some try I install some other modules:

apt-get install firmware-linux-nonfree
dpkg-reconfigure alsa-base
aslactl init
alsamixer

Into alsamixer giving F6 key I see that there were 2 sound card.
Now I see that I have two sounds card(exactly the same I see with the other commands by sheel).

Now clicking on the volume icon(sound preferences) I see also here(and I select it(under Output and Hardware tabs)) the view on the correct sound card(in my case Built-in Analog Stereo, and under connector the possibility to choose among Headphones or Speakers).

Now all seems solved....

Installing Debian on Lenovo G50...

I'm currently installing Debian 7.6.0 on my new Laptop Lenovo G50.
I execute the normal installation process starting from the net-inst distribution.

During the installation I needed to connect the net cable.
The wi-fi desn't been recognized.
Argh!!!!! (but this is another story in another post!!!)...
At the end of the installation a warning message notify me that gdm3 isn't started for some problems.

I see after, in a rapid check that also the the webcam in video modality has some problem(test with cheese application).

At the end of the process we have three problems to solve:
- wi-fi card unrecognized
- web-cam or video card to optimize
- gdm3 doesn't start

Next posts we try to solve these....

Bye..
