Hi all,

I'm new to kubuntu, and i quite like it, but I have a huge problem. I can't get any sound out of my laptop.
My laptop is an Acer 6920g.
This is the output of both lspci and lsmod:

This is the section in the bugfix that shows how to get sound. I would read through the whole thread though to get a better understanding of how everything turns out cuz I didn't read the whole thing.

Instructions that work for me:

sudo apt-get install alsa-source
cd /usr/src/
sudo tar xvjf alsa-driver.tar.bz2
cd modules/alsa-driver/
sudo ./configure --with-kernel=/usr/src/linux-headers-$(uname -r) --with-cards=hda-intel --with-oss=yes
cd alsa-kernel
sudo patch -p1 ... # repeat with all three patches
cd ..
sudo make
sudo make install

Now either reboot or reload all sound modules:

killall mixer_applet2 && sudo modprobe -r snd-hda-intel
sudo rmmod snd-seq-dummy snd-seq-oss snd-seq-midi snd-pcm-oss
sudo rmmod snd-mixer-oss snd-pcm snd-hwdep snd-rawmidi snd-seq-midi-event
sudo rmmod snd-page-alloc snd-seq
sudo rmmod snd-timer snd-seq-device
sudo rmmod snd
sudo rmmod soundcore
sudo depmod -a
sudo modprobe snd-hda-intel

Finally, use alsamixer to unmute the headphones & internal speakers, and set
PCM volume to something louder than 0%.

Light travels faster than the speed of sound. Thats why certain people appear bright till they open their mouths. "Where is the 'any' key?" – Homer Simpson, in response to the message, "Press any key" Registered Linux User # 475019

I don't realy understand how to install the patch. Where do I find "alsa-driver.tar.bz2"? I do need it to install the patch, right?

This afternoon, I descovered somthing strange. I touched the volume control of the cinedash panel on my acer laptop, and a volume bar appears on the screen, saying the volume is on 11%. In the sound settings screen, all sounds were set to 100%. (11% is the maximum volume. At that point, the cinedash panel's volume meter is full.)

I used kubuntu 7.10, but i reinstalled ubuntu this afternoon, and updated to 8.04, but still no sound.
If I right-click on the speaker icon, and choose preferences, "HDA Intel (Alsa Mixer)" is already selected.

My laptop is not in the list u posted.
