I expected the audio supported in Gutsy to work automagically in Hardy. It seems to be an integrated chipset on the motherboard. The motherboard is a MSI K7Turbo

[Michael Losonsky (michl)]

I have lots of problems with audio in ubuntu -- not the sound,
but recording, microphones, conferencing are all pretty
difficult to set-up and once you have it set-up, the next
update messes things up again. BUT this worked for
me in Hardy, to set everything to Pulseaudio instead of
ALSA. I am using an ATI Radeon card.

[Linuturk (linuturk)]

Where would I change these settings?

[Linuturk (linuturk)]

Well, I found those settings. My problem seems to be there is no device to use, according to the gnome control panel.

[Linuturk (linuturk)]

Please let me know if there is any additional information you need. My terminal is your terminal, as I say.

[Linuturk (linuturk)]

Some additional information. Per this thread: http://ubuntuforums.org/showthread.php?t=724042&highlight=sound+broke+hardy&page=2

When I boot to an older generic kernel, my sound works, but my nvidia card hates itself.

[Leann Ogasawara (leannogasawara)]

Hi Linuturk,

On the kernel where sound is broken, care to attach the output of alsa-info.sh which is available here: https://wiki.ubuntu.com/DebuggingSoundProblems . Thanks.

[Michael Losonsky (michl)]

I just upgraded on a Desktop from Gutsy to Hardy and have the very same
problem. The soundcard is not detected. This hasn't happened during
previous upgrades on this computer, a Dell precision workstation 220.

output of the alsa-info script is:
Your ALSA information is located at http://pastebin.ca/957596

Other log attached

[Michael Losonsky (michl)]

The thread below discusses this issue and offers a workaround that
worked for me. The problem is that when you upgrade, for some
reason two kernels are installed a 386 kernel and generic. The
sound problems are with the 386 kernel. Unfortunately, after
booting into the 386 kernel, it generates the initramfs file for
386, but messes-up the generic kernel, so you can't boot into
it anymore. (This is exactly what happened to me.) So you need
to run:
sudo update-initramfs -k 2.6.24-12-generic -c
in the terminal, and reboot into generic. The sound worked there for me.
Hope this works for you.

[Linuturk (linuturk)]

Here is the alsa info you requested.

[Linuturk (linuturk)]

Thank you Michael Losonsky.

The process he described worked perfectly. My sound is now working.

I've attached a new alsa-info.txt showing the system in the working state. The previous attachment is using the other kernel.

Is it safe to remove the 386 kernel?

[Linuturk (linuturk)]

Let me elaborate.

Should I uninstall the 386 kernel or just comment out it's entries in /boot/grub/menul.lst ?

[Igor Zubarev (igor.zubarev)]

I have the same problem after upgrade from Gutsy to Hardy. Intel built-in card on Sony VAIO VGN-FS115.

After apgrade Hardy didn't remove old Gutsy kernel and installed 386 kernel.
The problem with sound resolved:

sudo aptitude remove linux-image-2.6.24-12-386
sudo update-initramfs -k 2.6.24-12-generic -c

Many thanks to guys in http://ubuntuforums.org/showthread.php?t=729873

[Leann Ogasawara (leannogasawara)]

Hi Guys,

Unfortunately as you pointed out there were some issues occurring with upgrades where the i386 flavor was being installed instead of the generic flavor. See bug 188579. I'm going to go ahead and mark this as a duplicate of that. Thanks.

[W.McL (w-mcl)]

The sound issue after an upgrade also exists with 2.6.24-16-generic kernel.
Sound works on 2.6.24-16-386 though, but this breaks various other applications (mainly gnome related apps, so probably a X problem?)

[W.McL (w-mcl)]

My Problem was caused by the proprietary hsfmodem driver which was still present from gutsy and had renamed the original snd-intel-hda module.
Removing the hsfmodem driver solved the problem.

I have problems recording, kind of noisy. But I can hear my voice clear when I am recording, then when I reproduce it sounds noisy. I am using "Sound Recorder"
thanks!
