No sound with HDA Intel PCH

Solution 1:

For what it's worth, I've just resolved a no-sound problem on my HDA Intel PCH card: I ran 'alsamixer' in a terminal and unmuted the 'Line' column (with the M key).

Other info:

• I also made sure to unmute the Master, Headphone, Front, Surround, Center and LFE columns, but it's only when I unmuted Line that sound got out.
• The 'Chip' line in alsamixer says 'Realtek ALC887-VD'.
• The sound software never complained about the sound device.
• My system is Ubuntu 12.04. The speakers are connected to the green connector at the back of the PC.
• I tested the speakers with another computer.

Solution 2:

I had this same problem on my Asus K55A laptop, and I fixed it by doing the following:

open terminal and:

sudo nano /etc/modprobe.d/alsa-base.conf

at the end of the script add this line:

options snd-hda-intel model=pch position_fix=1

ctrl+x to exit

When you try to exit it will ask yout to save, enter "Y" then "Enter"

It will then ask you what file name you want to save it as, Do Not Change It!! Just hit "Enter"

Restart your machine and you should be good to go!!
