View Full Version : [ubuntu] No sound after upgrade to 9.10 Karmic

I know a few people have posted about this issue but I've not been able to get any suggestions to work from other threads. N00b here, please be gentle. ;)

The sound is an onboard Realtek AC97 chip on my motherboard. It worked absolutely fine on my 9.04 Jaunty setup. My machine is dual boot with Windows XP and the sound is fine on XP, so it's not a hardware issue.

Karmic seems to think there is no audio device present at all, which is obviously not the case.

This is an AMD 64-bit machine running the x64 edition, although I doubt that has anything to with the problem. Everthing else in the installation went perfectly and the GNOME desktop seems significantly quicker too.

Can anyone help me get my audio back?

There could be any number of problems. What do you see in the Sound panel (System --> Preference)? To begin to sort it out, post to the forum the outputs of these commands.
lspci
cat /etc/X11/xorg.confThat will tell us the hardware, and the configuration of the xserver, which uses the hardware to create sound.

Hope this helps, people. :)

It doesn't seem to be able to find my printer either (HP Photosmart 7760). Again, this worked on the previous installation (Jaunty 9.04) and still works on XP.

I see something strange, that I have seen on other forum posts about sound not working with this hardware. The card is listed as "CK804 AC'97 Audio Controller", the vendor is nVidia, but the driver that has claimed the card is Intel. I do not know if this is a problem, but it seems to me that perhaps there should be an nVidia driver for this card. I haven't found the answer yet, but maybe this is a clue.

It would be interesting if anybody with this card that has sound working could post their lshw output. I would like to see if the Intel driver claiming the card is a problem or not.

By the way, here is my lspci
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)and my sudo lshw -C sound:

Looking around, it seems that the Intel driver is the proper driver for this sound card. I am not sure, but I have never seen any other lshw outputs with a different driver. So I am stuck. Maybe try the Multimedia and Video forum. Post a link there to this thread.

I am also having trouble with 9.10 and sound -- there was no sound when I first installed it, then it magically healed itself (after an update somewhere along the line), then it died again (I suspect after another update...). I'm replying to this message because the output of lshw you list is exactly what it produces on my machine, an old Toshiba Tecra -- So it gave me hope that *someone* had gotten sound working with this card!

I'll attach my xorg.conf and lspci output as well, in the hope that someone can help.

Thanks to anyone who can!

Sorry, no specific help, but you might take a look at this sticky thread (http://ubuntuforums.org/showthread.php?t=1307019). You can search inside the thread to see if there is a similar lshw output that has the same problem.

One problem mentioned at the start of that sticky thread is that grub 2 is sometimes booting the wrong kernel. A true Karmic kernel should start with 2.6.31, but a Jaunty kernel would be 2.6.28. You can see which kernel is actually running with the command
uname -r

I have tried everything I can find in the Forums, but nothing seems to work.

I am a new user to Linux, and am getting to like it. However, if i can't get the sound working I will be forced to go back to Windows (not ideal).

If anyone can help it would be appreciated.

here's the answer to your problem:

sudo alsa force-reloadIf it's still not working, then:

alsamixer -c0 and make sure front, headphone and PCM are at their highest level.

When I upgraded ubuntu 9.04 to 9.10, my sound was not working till I checked my volume control and found out that it was muted. It's like it got muted during or due to the upgrade. Maybe it's a rare occurrence but just check it might just be mute.

i am also a fairly new ubuntu user with no sound after upgrade to 9.10. below is the info:

configuration: driver=HDA Intel latency=0

what's odd is that i still hear the little asus startup melody on bootup, i just can't get sound from anything else after all the drivers load. the sound worked fine until one of the 9.10 tuneups. all my regular sound controls are what they should be, nothing is muted and volume is up. can anyone tell anything from the data above?

thanks for any help!

Hi mates,

I installed the Ubuntu 9.04 and have the same problem - no sound. In my older 8.04 version I managed it with experimenting with the sound preferences panel (System->Preferences->Sound). Now it does not seem to help.

By the way my built in microphone works, so when I say something close to the microphone i hear it in the speakers. However when I play an mp3 or youtube - nothing....

If somebody has found a solution..?

Trying some commands gave me to followin information about my system:
1.
asoundconf list

Result:
SIS966

2.
sudo lshw -C sound

Result:

Go to System>Administratio>Software Sources and open 'Backports', 'Updates, 'Proposed', etc sources. Then do:

sudo apt-get update
sudo apt-get dist-upgrade

I had the sound issue after the upgrade and it was because like dstew was saying the problem ended up being that the wrong kernel was running despite the fact that updated kernels were installed. I beleive that created a situation where packages were missmatched against the kernel that was actually running. I solved it by completely removing the new kernel and reinstalling it (which i did all from Synaptic Package Manager). Like dstew said, run "uname -r". It should print out "2.6.31-17-generic" if your system is updated (as of the time of this post).

I have the same problem when I updated from 9.04 to 9.10.
The kernel I am running is 2.6.28-17. I'm pretty sure this is a kernel issue, but I don't know much about Ubuntu at the moment. If it installed a kernel that isn't being used witch one should I use?

Hi im a noob here as well but I also had a simelar problem to this I was using a Dell 9.04 ubuntu and upgraded from the update manager lost all sound driver was not recognised.
So I did a full install after i downloaded the 9.10 iso everything worked even my remote control that didnt work in 9.04 So I would try that if you can, on other threads it seems to suggest as the best option.. :D

I've just freshly installed Ubuntu 9.10 on my laptop.
(Belinea C1541)


Which has a Silicon Integrated Systems [SiS] Azalia Audio Controller/ HDA SIS966 Chip: Realtek ALC662 rev1
And noticed that my sound was missing.

However; succeeded to get my sound working by adding


options snd-hda-intel model=laptop

to [
/etc/modprobe.d/alsa-base.conf .

(for new users: gksudo gedit /etc/modprobe.d/alsa-base.conf) scroll down to the options listed and add the above option to it, save the file and reboot.)

EDIT: I noticed my sound stopped working randomly and at first I blamed it on pulseaudio, However, by removing my pulseaudio the problem was not fixed/ so I reinstalled it , since I actually like to use it.

I reinstalled alsa-base to see If that was it, However... Sound just stopped working randomly again

After some time on google I changed
options snd-hda-intel power_save=10 power_save_controller=N to
options snd-hda-intel power_save=0 power_save_controller=N

in /etc/modprobe.d/alsa-base.conf

Seems to work out, sound has not stopped since then.
