No sound no matter what I try in Jaunty

[Stu]

I upgraded to Jaunty at the end of last week and I now have no music through my headphones. Weirdly I do get the system beep through my headphones when I try to tab-complete something with more than one match in a terminal, etc.

I've gone through the steps outlined in numerous bugs, but they don't seem to cover my specific problem.

My levels in alsamixer are all set to 100. I've checked out gnome-alsamixer and nothing is muted in there. Also, none of the options are checked underneath the volume controls. I don't really know if any of them need to be checked at all.

I installed the pulse audio tools and followed the instructions in this post: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/301261/comments/21 but to no effect. I've also followed the instructions on this page: http://platonic.techfiz.info/2009/01/22/fixed-no-sound-on-ubuntu-904-alpha2/ and the instructions on this page that were for 8.10: http://onlyubuntu.blogspot.com/2008/11/fix-for-no-sound-issue-in-ubuntu-810.html

aplay -l gives me the following:

$ aplay -l

soundcore 15200 1 snd
snd_page_alloc 16904 2 snd_hda_intel,snd_pcm

I haven't got a clue what else to try. Plus I'm fairly sure that now I've changed so many things I've probably ended up doing more harm than good.

Hi Stu,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid.

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 367818

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
