Linux Mint 17 not sound

[aguila3000]

I have Linux Mint 17 installed on my computer that has the following characteristics:

Motherboard: intel DQ35JOE
CPU: intel core 2 quad Q6600-B1066 2.4 GHz 8MB
RAM: 2 GB DDR2 B800
Hard Drive: 160 GB Sata
Video card: Gigabyte GTX 560 1GB DDR5

The installation ok, but the problem is it does not recognize the audio from the motherboard.
I've tried removing the video card and does not recognize the audio from the motherboard.
According to the manuals DQ35JOE, the audio is a Realtek ALC268-GR *.
I need help.

thank you

Hi!
Maybe you will find a hint in my help (see signature), chapter 5, sound.

Thanks for your help.
But none of what you say in your notes, helped me.

I added the following line to the end of the file "alsa-base.conf"

Code: Select all

options snd-hda-intel model=auto

And got the following output for the following commands:

dmesg | grep snd

Code: Select all

[   14.977661] snd_hda_intel 0000:00:1b.0: irq 48 for MSI/MSI-X

dmesg | grep sound

Code: Select all

NOT SOUND. PLEASE HELP.

Did you try

Code: Select all

cat /proc/asound/card0/codec#* | grep Codec

and afterwards searching in the forum and the Net for that Codec? Maybe you'll find a clue.

I upgraded from Mint 14 to Mint 17 and the sound stopped working. I have a Lenovo Thinkpad with a HDA Intel and Thinkpad EC/Thinkpad Console Audio Control audio adapters.

After trying the standard sound settings and searching onine I installed pavucontrol

Code: Select all

sudo apt-get install pavucontrol

In the last tab, Settings, I scrolled through the profiles, and re-selected Duplex Analogue Stereo, which it was on anyway. The process of re-selecting it fixed the sound. Hope this might help.
