No sound after kernel upgrade

Bug Description

After a kernel upgrade to linux-image-2.6.32-61-generic sound has stopped working. Sound applications hang and no sound is produced. "ubuntu-bug -s audio" does produce the first test tone but not the second one. Any subsequent attempt to close apport then causes it to stop responding. After rebooting with the previous kernel (linux-image-2.6.32-60-generic) sound works as before.

Machine is a Dell E5500 laptop with HDA-Intel sound hardware.

An attempt to run "apport-collect 1327220" to gather more information resulted in the following error message:

Error connecting to Launchpad: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<title>404 Not Found</title>
<h1>Not Found</h1>
<p>The requested URL /+request-token was not found on this server.</p>

You can reset the credentials by removing the file "/home/jacco/.cache/apport/launchpad.credentials"

The indicated file "/home/jacco/.cache/apport/launchpad.credentials" does not exist.

Ubuntu version is 10.04.4 LTS by the way.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1327220

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

Hi Jaco,
i had the same problem today.

There is a "turn around" solution for this:

At the boot screen, you can choose the version of the Kernel that you want to use. I choose this: 2.6.32-60-generic

I recomend that you choose the version before the "problematic one" :P

I also disabled the automatic updates at Synaptic.

If you want to turn the "solution" more permanent, you can also edit (make a backup copy before) the file /etc/default/grub and change the value of GRUB_DEFAULT to 2. Then de boot loader will load the 3rd boot option (first is 0). Run update-grub and reboot to see if work.

PS: If you keep the automatic updates on, when it setup a new version of kernel, it will override this modification at grub.

Neither audio nor video works after upgrading to kernel 2.6.32-61.
Applications like Firefox, vlc, totem, rhythmbox etc. totally freezes when trying to play videos (flash, mp4 etc.) or audio, and have to killed. Can't find anything particular in kernel and system logs.
2.6.32-61 is unusable on my old desktop, normally not connected to internet (I'm well aware that the 10.04 desktop version is unsupported...). For the time being I'll continue to use 2.6.32-60.

Jacco van Schaik, thank you for reporting this bug to Ubuntu. Lucid Desktop reached EOL on May 9, 2013.
See this document for currently supported Ubuntu releases:

Please upgrade to the latest version and re-test. If the bug is still reproducible, please file a new report via a terminal:
ubuntu-bug linux

Please feel free to report any other bugs you may find.

I'm getting the same trouble as Mikael running linux-image-2.6.32-61-server on multiple machines.

I didn't try sound but firefox for sure locks it up. Ctrl-Alt-F1 to a console still works as does ssh, where you can kill the X server and get back to the login screen. Mouse works but clicking on things becomes unresponsive.

rebooting and selecting linux-image-2.6.32-60-server with grub gets it back to a usable state, but there is definitely something amiss in the new kernel image.

nVidia proprietary driver is being used by both systems locking up (both AMD PhenomII X6).

this is present in lucid server too, which continues to be supported. Reopening.
 (where else would Jacco have gotten the new package upgrade anyway?)

Whereas this bug #1327220's status has now transitioned from invalid->confirmed (Thank You!), the duplicate bug 1327014 remains invalid.

For me, the problem has been fixed in kernel version 2.6.32-62.

For me the kernel from lucid-proposed (2.6.32-62.125) also fixed this problem.
The cause and fix for the problem are described in
