View Full Version : [ubuntu] Sound stopped working on Ubuntu, need help fixing

September 16th, 2009, 02:00 AM

I have a Lenovo IdeaPad Y530. I tried to find more information on my computer's operating parameters, but with no success so far. (I suppose I can find that out in a terminal, but I don't know what command to type in.)

Anyway, earlier this summer I switched my operating system from Windows to Ubuntu 8.4 (I'm pretty sure it's the .4). For a while it worked fine, then, after a couple weeks, the sound stopped working. It still plays music when I boot up, so I know the trouble's not with the hardware, it's with Ubuntu.

Everything in the volume control is unmuted and running full blast. Not a peep.

I've tried consulting the Comprehensive Sound Problems Solutions Guide here: http://ubuntuforums.org/showthread.php?t=205449. I got as far as Step 3, which instructed me to go to a website (http://www.alsa-project.org/alsa-doc/) and “search for your sound card (chipset) manufacturer in the dropdown box.”

I couldn't find a dropdown box, but a link in the Parent Directory which said “Is my soundcard supported?” I clicked this, and then clicked “Intel” for the manufacturer.

From Step 2 of the Comprehensive Sound Problems Solutions Guide I know that my Audio device is an ICH9 Family, which is not listed on the soundcard list for Intel. The Guide says that “If you don't find the driver, I can't help you.”

However, I know my soundcard can work with this version of Ubuntu, so that means the problem should be fixable, right?

I also googled my Audi device's information from the terminal window (“Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
”) and came across this: http://ubuntuforums.org/showthread.php?t=940689.

This, in a nutshell, was the advice:

“open a terminal;
sudo gedit /etc/modprobe.d/alsa-base
give your password when asked;
it's normal that nothing is shown when you are writing your password;
a text document will open;
all you have to do is to past the three lines at the end of the text document;
and finally reboot your system.”

The three lines in question being:

“options snd-hda-intel model=3stack-dig
options snd-hda-intel enable_msi=1
options snd-hda-intel single_cmd=1”

I have followed these instructions and had no luck. I am now at my wits' end. Anybody have some ideas?
